Nitrat ist die höchstoxidieren<strong>de</strong> Stufe <strong>de</strong>s<br />

Stickstoffkreislaufs. Es ist vielerorts bereits im<br />

Leitungswasser in größerer Menge vorhan<strong>de</strong>n.<br />

Nitrat entsteht im Aquarium zusätzlich durch die<br />

Abbauprodukte <strong>de</strong>r Fische und starke Fütterung.<br />

Hohe organische Belastung führt zu hohem<br />

Nitrat-Gehalt.<br />

Zwar benötigen Pflanzen Nitrat als Nährstoff,<br />

doch ein Überangebot an Nitrat scha<strong>de</strong>t <strong>de</strong>n<br />

Pflanzen und ist eine <strong>de</strong>r Ursachen <strong>de</strong>r Cryptocorynenfäule.<br />

Bei CO 2 -Mangel besteht die<br />

Gefahr, daß das Nitrat zu giftigem Nitrit reduziert<br />

wird. Doch das größte Problem sind die Algen,<br />

die bei einem Nitrat-Überangebot leicht außer<br />

Kontrolle geraten.<br />

Deshalb muß <strong>de</strong>r Nitratgehalt <strong>de</strong>s Aquariumwassers<br />

regelmäßig gemessen wer<strong>de</strong>n. Es geht<br />

leicht und bequem mit einem <strong>de</strong>r im Zoofachhan<strong>de</strong>l<br />

angebotenen NO 3 -Tests.<br />

Im Süßwasseraquarium ist ein Nitratwert unter<br />

50 mg/l anzustreben. 80 mg/l sollten möglichst<br />

nicht überschritten wer<strong>de</strong>n. 150 mg/l sind in<br />

je<strong>de</strong>m Fall zuviel.<br />

amtra nitrat-reduct senkt einen zu hohen<br />

Nitratwert sicher und schnell auf <strong>de</strong>m Wege<br />

<strong>de</strong>s Ionenaustauschs und gibt das Nitrat auch<br />

nach Erschöpfung <strong>de</strong>s Materials nicht wie<strong>de</strong>r an<br />

das Aquariumwasser ab. 250 (500) ml bin<strong>de</strong>n<br />

bis zu 7000 (14000) mg innerhalb von ein bis<br />

zwei Tagen.<br />

amtra nitrat-reduct ist umweltschonend und<br />

sparsam, <strong>de</strong>nn es kann mit einer Kochsalzlösung<br />

einfach regeneriert und dadurch mehrmals<br />

Anwendung:<br />

amtra nitrat-reduct mit <strong>de</strong>m Netzbeutel in <strong>de</strong>n<br />

Filter legen. Nach ein bis zwei Tagen Nitratwert<br />

messen. Liegt er noch über <strong>de</strong>m gewünschten<br />

Wert, amtra nitrat-reduct regenerieren und<br />

erneut einsetzen.<br />

Regenerieren:<br />

100 g nicht jodiertes Kochsalz in ein Gefäß mit<br />

1 l Wasser geben. Netzbeutel mit amtra nitratreduct<br />

für ein bis zwei Tage hineinlegen und anschließend<br />

in reichlich frischem Wasser gründlich<br />

spülen. Nach je<strong>de</strong>r Aufbereitung verringert sich<br />

<strong>de</strong>r Wirkungsgrad um ca. 10%. Deshalb sollte<br />

amtra nitrat-reduct nicht öfter als drei- bis<br />

viermal regeneriert wer<strong>de</strong>n.<br />

amtra nitrat-reduct ist nicht für <strong>de</strong>n Einsatz<br />

im Meerwasser geeignet. Der Nitratwert <strong>de</strong>s<br />

Leitungswassers kann jedoch vor <strong>de</strong>r Aufbereitung<br />

zu Meerwasser mit amtra nitrat-reduct<br />

Nitraat is <strong>de</strong> hoogst geoxi<strong>de</strong>er<strong>de</strong> fase van <strong>de</strong><br />

stikstofkringloop. Op vele plaatsen is dit in het<br />

leidingwater al in grotere hoeveelhe<strong>de</strong>n anwezig.<br />

Door sterke voe<strong>de</strong>ring en afbraakstoffen van <strong>de</strong><br />

vissen ontstaat eveneens nitraat. Een hoge organische<br />

belasting leidt tot een hoog nitraatgehalte.<br />

Nitraat is weliswaar een voedingsstof voor <strong>de</strong><br />

planten, maar teveel nitraat is scha<strong>de</strong>lijk en<br />

bovendien een van <strong>de</strong> oorzaken voor crytocoryneenrotting.<br />

Bij gebrek aan CO 2 bestaat het<br />

gevaar, dat het nitraat wordt gereduceerd tot<br />

het giftige nitriet. Maar het grootste probleem<br />

vormt <strong>de</strong> algengroei die bij een teveel aan nitraat<br />

snel uit <strong>de</strong> hand kan lopen.<br />

Daarom moet het nitraatgehalte van het aquariumwater<br />

regelmatig wor<strong>de</strong>n gemeten. Dit gaat<br />

heel eenvoudig met een van <strong>de</strong> NO 3 -tests, die<br />

in <strong>de</strong> dierenspeciaalzaak wor<strong>de</strong>n aangebo<strong>de</strong>n.<br />

In het zoetwateraquarium wordt een nitraatwaar<strong>de</strong><br />

van min<strong>de</strong>r dan 50 mg/l geadviseerd,<br />

maar in ie<strong>de</strong>r geval moet 80 mg/l niet wor<strong>de</strong>n<br />

Gebruik:<br />

amtra nitrat-reduct in het netje in <strong>de</strong> filter<br />

leggen en af en toe bewegen. Daarna met veel<br />

schoon water grondig uitspoelen. Na ie<strong>de</strong>re<br />

opwerking wordt <strong>de</strong> werking met 10% vermin<strong>de</strong>rd.<br />

Het is daarom zinvol, amtra nitratreduct<br />

niet vaker dan drie- of viermaal te<br />

amtra nitrat-reduct is niet geschikt voor <strong>de</strong><br />

Nitrate is the most highly oxidised stage of the<br />

nitrogen cycle. In many areas it is present in tap<br />

water in large quantities. Nitrate is also produced<br />

in aquariums by the breakdown products of the<br />

fish and heavy feeding levels. High levels of<br />

organic matter lead to high quantities of nitrate.<br />

Plants require nitrate as a nutrient, however<br />

excessive nitrate levels are harmful to plants<br />

and are one of the ca<strong>use</strong>s of cryptocoryne<br />

rot. Where too little CO 2 is present there is a<br />

risk of the nitrate being reduced to toxic nitrite.<br />

However, the greatest problem is algal growth<br />

which can easily become uncontrollable<br />

where nitrate levels are too high.<br />

The nitrate content of aquarium water should<br />

there<strong>for</strong>e be regularly tested. This can be done<br />

easily with an NO 3 test available from specialist<br />

pet shops.<br />

Nitrate values should i<strong>de</strong>ally be less than 50<br />

mg/l in freshwater aquariums. 80 mg/l should<br />

not be excee<strong>de</strong>d. 150 mg/l is <strong>de</strong>finitely too high.<br />

amtra nitrat-reduct reduces nitrate levels<br />

quickly and safely through ion exchange<br />

without releasing the nitrate back into the<br />

aquarium water once the active life of the<br />

material is over. 250 (500) ml binds up to<br />

7000 (14000) mg within one or two days.<br />

amtra nitrat-reduct is environmentfriendly<br />

and economical as it can simply be regenerated<br />

and <strong>use</strong>d several times over.<br />

Application:<br />

Place amtra nitrat-reduct in its net into the<br />

filter. Measure the nitrate levels after one or<br />

two days. If it is still higher than the <strong>de</strong>sired<br />

value, regenerate the amtra nitrat-reduct<br />

and put it back into the filter.<br />

Regeneration:<br />

Put 100 g of table salt without iodine in a<br />

container with 1 litre of water. Insert the net<br />

containing the amtra nitrat-reduct into the<br />

solution <strong>for</strong> one or two days, stirring occasionally.<br />

Afterwards rinse thoroughly using plenty of fresh<br />

water. The effectiveness is reduced by roughly<br />

10% by this process which is why amtra nitratreduct<br />

should not be regenerated more than<br />

three or four times.<br />

amtra nitrat-reduct is not suitable <strong>for</strong> <strong>use</strong><br />

in seawater. However, the nitrate level of the<br />

tap water can be lowered with amtra nitratreduct<br />

be<strong>for</strong>e trans<strong>for</strong>ming it into seawater.<br />

Package size:<br />

Les nitrates correspon<strong>de</strong>nt à la phase la plus<br />

oxydée du cycle <strong>de</strong> l’azote. Dans beaucoup d’endroits,<br />

l’eau du robinet contient déjà une gran<strong>de</strong><br />

quantité <strong>de</strong> nitrates. Or, dans le aquariums, <strong>de</strong>s<br />

nitrates apparaissent en plus à ca<strong>use</strong> <strong>de</strong>s déchets<br />

organiques <strong>de</strong>s poissons et d’une abondance <strong>de</strong><br />

nourriture. Une quantité élevée <strong>de</strong> ces déchets<br />

provoque une trop <strong>for</strong>te concentration <strong>de</strong> nitrates.<br />

Les plants ont certes besoin <strong>de</strong> nitrates pour se<br />

nourrir, mais dans une proportion trop <strong>for</strong>te,<br />

ces nitrates nuisent aux plantes et sont l’une <strong>de</strong>s<br />

raisons <strong>de</strong> la pourriture <strong>de</strong>s cryptocorynes. Si<br />

la teneur en CO 2 est insuffisante, les nitrates<br />

risquent <strong>de</strong> se réduire en nitrites toxiques. Or,<br />

lorsque la concentration <strong>de</strong> nitrates est trop importante,<br />

les algues sont très difficiles à maîtriser.<br />

Par conséquent, il faut mesurer régulièrement le<br />

taux <strong>de</strong> nitrates dans l’eau <strong>de</strong> l’aquarium. Ceci<br />

est simple et facile à faire grâce aux test NO 3<br />

proposés dans les magasins spécialisés en<br />

aquariophilie.<br />

Dans un aquarium d’eau douce, il est recommandé<br />

<strong>de</strong> maintenir le taux nitrates en <strong>de</strong>ssous<br />

<strong>de</strong> 50 ml/l. Il convient <strong>de</strong> ne pas dépasser si<br />

possible 80 mg/l. Un taux <strong>de</strong> 150 mg/l est en<br />

tout cas beaucoup trop élevé.<br />

amtra nitrat-reduct réduit un taux <strong>de</strong> nitrates<br />

trop élevé <strong>de</strong> manière sûre et rapi<strong>de</strong> par échange<br />

d’ions et même lorsque sa capacité d’absorption<br />

est épuisée, il ne rejette pas le nitrates dans l’eau<br />

<strong>de</strong> l’aquarium. 250 (500) ml absorbent jusqu à<br />

7000 (14000) mg <strong>de</strong> nitrates en un à <strong>de</strong>ux jours.<br />

amtra nitrat-reduct est économique et favorable<br />

à l’environnement, car une solution à<br />

base d’eau salée permet <strong>de</strong> le régénérer et par<br />

conséquent <strong>de</strong> le réutiliser plusieurs fois.<br />

Utilisation:<br />

Mettre le produit amtra nitrat-reduct avec le<br />

filet dans le filtre. Mesurer le taux <strong>de</strong> nitrates un<br />

à <strong>de</strong>ux jours plus tard. Si le taux mesuré est<br />

encore supérier au taux souhaité, régénérer<br />

simplement le produit et le remettre en œuvre.<br />

Régénération:<br />

Mettre 100 g <strong>de</strong> sel non jodé dans un récipient<br />

avec 1 l d’eau. Mettre le filet avec le produit<br />

amtra nitrat-reduct dans cette eau salée pendant<br />

un à <strong>de</strong>ux jour et le remuer <strong>de</strong> temps en<br />

temps. Rincer ensuite le produit dans une gran<strong>de</strong><br />

quantité d’eau fraîche. Après chaque traitement,<br />

sa capacité d’absorption diminue d’environ<br />

10%. Aussi, il convient <strong>de</strong> ne pas régénérer<br />

amtra nitrat-reduct plus <strong>de</strong> trois à quatre<br />

fois.<br />

amtra nitrat-reduct ne convient pas pour l’eau<br />

<strong>de</strong> mer. La teneur en nitrates <strong>de</strong> l’eau du robinet<br />

peut toutefois être abaissée avec <strong>de</strong> l’amtra<br />

nitrat-reduct avant le traitement en eau <strong>de</strong> mer.<br />

Emballage:<br />

Il nitrato è il gradino tossico più alto <strong>de</strong>l ciclo<br />

<strong>de</strong>ll’azoto. In molte regioni esso è già presente<br />

in notevole quantità nell’acqua potabile. Il<br />

nitrato si <strong>for</strong>ma inoltre nell’acquario attraverso<br />

gli escrementi <strong>de</strong>i presci e l’abbondanza di mangime.<br />

Una quota elevata di materiale organico<br />

porta alla <strong>for</strong>mazione di valori alti di nitrato.<br />

Le piante hanno bisogno di nitrato come sostanza<br />

nutritiva, però una sovrabbondanza di nitrato fa<br />

male ad esse ed è una <strong>de</strong>lle ca<strong>use</strong> <strong>de</strong>l putredine<br />

<strong>de</strong>i criptocorini. Dalla mancanza di CO 2 c’è il<br />

pericolo che il nitrato viene ridotto nel velenoso<br />

nitrito. Però il più gran<strong>de</strong> problema sono le alghe<br />

che, alla presenza di nitrato in sovrabbondanza,<br />

possono facilmente diventare incontrollabili.<br />

Per questo il valore <strong>de</strong>l nitrato <strong>de</strong>ll’acqua<br />

<strong>de</strong>ll’aquario <strong>de</strong>ve essere regolarmente controllato.<br />

E’possibile farlo facilmente e comodamente<br />

con il test NO 3 che viene offerto nei negozi<br />

specializzati.<br />

Negli acquari d’acqua dolce bisogna cercare<br />

di arrivare ad un valore di nitrato al di sotto<br />

di 50mg/l. 80 mg/l non dovrebbero essere<br />

superati. 150 mg/l sono in ogni caso troppo.<br />

amtra nitrat-reduct abbasssa un valore di<br />

nitrato troppo alto in modo sicuro e rapido, sulla<br />

base <strong>de</strong>llo scambio di ioni e non ridà il nitrato<br />

all’acqua <strong>de</strong>ll’acquario, neanche dopo l’esaurimento<br />

<strong>de</strong>l materiale, 250 (500 ) ml legano fino<br />

a 7000 (14000) mg nel giro di uno, due giorni.<br />

amtra nitrat-reduct è economico ed aconomico,<br />

perché esso può essere rigenerato in una<br />

soluzione di sale e quindi può essere usato più<br />

volte.<br />

Uso:<br />

Immettere amtra nitrat-reduct nel filtro insieme<br />

alle rete che lo avvolge. Dopo uno fino a due<br />

giorni misurare il valore <strong>de</strong>l nitrato. Se è ancora<br />

al di sopra <strong>de</strong>l valore <strong>de</strong>si<strong>de</strong>rato, rigenerare<br />

l’amtra nitrat-reduct ed immettere di nuovo<br />

nel filtro.<br />

Rigenerazione:<br />

Immettere 100 g di sale senza iodio in un recipiente<br />

con 1 litro d’acqua. Mettere <strong>de</strong>ntro la rete<br />

contenente l’amtra nitrat-reduct per uno fino a<br />

due giorni e di tanto in tanto agitare. Alla fine<br />

sciacquare accuratamente in abbondante acqua<br />

fresca. Dopo ogni rinnovo diminuisce il grado<br />

d’azione di circa il 10%. Per questo non si<br />

dovrebbe rigenerare l’amtra nitrat-reduct più<br />

di tre, quattro volte.<br />

amtra nitrat-reduct non è indicato per l’impiego<br />

in acqua marina. Il valore <strong>de</strong>l nitrato<br />

<strong>de</strong>ll’acqua potabile può essere abbassato con<br />

amtra nitrat-reduct prima <strong>de</strong>lla preparazione<br />

ad acqua di mare.<br />

Contenuto <strong>de</strong>l pacco:<br />

250 (500) ml in sacchetto a rete, sufficiente<br />

El nitrato correspon<strong>de</strong> a la fase <strong>de</strong> mas alta oxidactión<br />

en el ciclo <strong>de</strong>l nitrógeno. Según los lugares,<br />

el agua <strong>de</strong> grifo contiene una concentractión consi<strong>de</strong>rable<br />

<strong>de</strong> nitratos. En el acuario, el nitrato se<br />

<strong>for</strong>ma adicionalmente a través <strong>de</strong> las excreciones<br />

<strong>de</strong> los peces y <strong>de</strong>bido a una alimentación abundante.<br />

El recargo orgánico Ileva aparejado una<br />

elevada concentración <strong>de</strong> nitrato.<br />

Si bien es verdad que las plantas precisan substancias<br />

nutritivas, el contenido excesivo <strong>de</strong> nitrato<br />

daña las plantas y es un motivo <strong>de</strong> la putrefacción<br />

<strong>de</strong> criptocorinas. En el caso <strong>de</strong> falta <strong>de</strong> CO 2 existe<br />

el riesgo <strong>de</strong> que el nitrato se reduzca a nitrito,<br />

substancia <strong>de</strong> características tóxicas. Sin embargo,<br />

el problema principal lo constituyen las algas que<br />

en el caso <strong>de</strong> una presencia excesiva <strong>de</strong> nitrato<br />

pue<strong>de</strong>n convertirse fácilmente en una plaga<br />

incontrolable.<br />

Por consiguiente, el contenido <strong>de</strong> nitrato se ha<br />

<strong>de</strong> medir períodicamente. Ello se pue<strong>de</strong> hacer<br />

muy fácilmente con un test <strong>de</strong> NO 3 tal como lo<br />

ofrecen las tiendas especializadas.<br />

En el acuario <strong>de</strong> agua dulce se ha <strong>de</strong> cuidar <strong>de</strong><br />

que el valdor <strong>de</strong> nitrato se mantenga <strong>de</strong>bajo <strong>de</strong><br />

50 mg/litro. En lo posible, el valor <strong>de</strong> 80 mg/litro<br />

no <strong>de</strong>bería exce<strong>de</strong>rse nunca. 150 mg/litro supone<br />

un valor <strong>de</strong>masiado elevado.<br />

amtra nitrat-reduct reduce el valor <strong>de</strong> nitrato<br />

rápida y seguramente a través <strong>de</strong> un intercambio<br />

<strong>de</strong> iones, sin <strong>de</strong>volver el nitrato al aqua <strong>de</strong>l<br />

acuario aunque la capacidad <strong>de</strong> absorción <strong>de</strong>l<br />

material esté agotada. 250 (500) ml fijan hasta<br />

7000 (14000) mg <strong>de</strong>ntro <strong>de</strong> uno a dos días.<br />

amtra nitrat-reduct es un producto comptible<br />

con el medico ambiente y muy económico, ya<br />

que es sencillamente regenerable en aqua<br />

salada, permitiendo así, su uso reiterado.<br />

Empleo:<br />

Colocar amtra nitrat-reduct con la re<strong>de</strong>cilla en<br />

el filtro. Medir el valor <strong>de</strong> nitrato <strong>de</strong>spués <strong>de</strong> uno<br />

o dos días. De no obtenerse el valor <strong>de</strong>seado,<br />

regenerar amtra nitrat-reduct y volver a<br />

colocar.<br />

Regeneración:<br />

Colocar 100 g <strong>de</strong> sal común no yodada en un recipiente<br />

con 1 l <strong>de</strong> agua. Colocar la re<strong>de</strong>cilla<br />

con amtra nitrat-reduct en el recipiente durante<br />

uno o dos días y agitar <strong>de</strong> vez en cuando. A<br />

continuación enjuagar muy bien con agua pura.<br />

Después <strong>de</strong> cada tratamiento, la capacidad <strong>de</strong><br />

absorción disminuye en aprox. un 10%. Por ello,<br />

amtra nitrat-reduct no <strong>de</strong>bería regenerarse<br />

más <strong>de</strong> tres a cuatro veces.<br />

amtra nitrat-reduct no es apto para ser empleado<br />

en agua <strong>de</strong> mar. Sin embargo, el contenido<br />

<strong>de</strong> nitrato <strong>de</strong>l agua <strong>de</strong> grífo pue<strong>de</strong> reducirse con<br />

amtra nitrat-reduct si se emplea antes <strong>de</strong>l tratamiento<br />

necesario para obtener agua <strong>de</strong> mar.<br />

Tamaño:<br />

250 (500) ml en una re<strong>de</strong>cilla, suficiente para<br />

O nitrato é o estágio <strong>de</strong> oxidação máxima da<br />

circulação do azoto. Em muitas regiões ele existe<br />

já em gran<strong>de</strong>s quantida<strong>de</strong>s na água da canalização.<br />

No aquário ele se <strong>for</strong>ma adicionalmente<br />

através dos produtos <strong>de</strong> <strong>de</strong>composição dos peixes<br />

e através da exagerada dosagem <strong>de</strong> ração. Uma<br />

elevada carga <strong>de</strong> produtos orgânicos provoca<br />

um elevado teor <strong>de</strong> nitrato.<br />

Apesar das plantas necessitarem <strong>de</strong> nitrato como<br />

substância nutritiva, o excesso <strong>de</strong>ste elemento<br />

po<strong>de</strong>, contudo, prejudicar as plantas sendo ainda<br />

uma das causas da putrefacção <strong>de</strong> criptocorinas.<br />

Na falta <strong>de</strong> CO 2 existe o perigo que o nitrato se<br />

reduza em nitrito tóxico. Porém, o maior problema<br />

são as algas que, no caso <strong>de</strong> um teor excessivo <strong>de</strong><br />

nitrato, po<strong>de</strong>m crescer <strong>de</strong>scontroladamente.<br />

Por isso, o teor <strong>de</strong> nitrato da água do aquário tem<br />

que ser periodicamente medido. Esta medição<br />

po<strong>de</strong> ser efectuada facilmente e comodamente<br />

empregando-se um dos testes <strong>de</strong> NO 3 que estão<br />

à venda nas lojas especializadas.<br />

Nos aquários <strong>de</strong> água doce <strong>de</strong>ve-se tentar manter<br />

um teor <strong>de</strong> nitrato abaixo <strong>de</strong> 50 mg/l. Na medida<br />

do possível, aconselha-se não exce<strong>de</strong>r um teor <strong>de</strong><br />

80 mg/l. Um teor <strong>de</strong> 150 mg/l já é consi<strong>de</strong>rado<br />

como excessivo.<br />

amtra nitrat-reduct reduz <strong>de</strong> <strong>for</strong>ma segura e<br />

rápida teores <strong>de</strong> nitrato muito elevados, mediante<br />

a troca iónica, não remetendo-o novamente na<br />

água do aquário, mesmo <strong>de</strong>pois do esgotamento<br />

do material activo. 250 (500) ml fixam até 7000<br />

(14000) mg no prazo <strong>de</strong> um até dois dias.<br />

amtra nitrat-reduct é um produto compatível<br />

ao meio ambiente e económico, pois ele po<strong>de</strong><br />

ser facilmente regenerado com uma solução <strong>de</strong><br />

sal <strong>de</strong> cozinha para ser aplicado várias vezes.<br />

Aplicação:<br />

Colocar o saquinho <strong>de</strong> re<strong>de</strong> com amtra nitratreduct<br />

no filtro. Depois <strong>de</strong> um até dois dias medir<br />

o teor <strong>de</strong> nitrato. Se o teor ainda <strong>for</strong> superior ao<br />

valor <strong>de</strong>sejado, regenerar o produto amtra nitratreduct,<br />

con<strong>for</strong>me <strong>de</strong>scrito, e empregá-lo<br />

novamente.<br />

Regeneração:<br />

Misturar num recipiente 100 g <strong>de</strong> sal <strong>de</strong> cozinha<br />

não iodizado com 1 l <strong>de</strong> água. Colocar <strong>de</strong>ntro do<br />

recipiente o saquinho <strong>de</strong> re<strong>de</strong> com amtra nitratreduct<br />

e <strong>de</strong>ixar actuar durante um até dois dias e<br />

agitando-o <strong>de</strong> vez em quando. Depois enxaguar<br />

bem o saquinho <strong>de</strong> re<strong>de</strong> com bastante água<br />

fresca. Em cada operação <strong>de</strong> regeneração reduzse<br />

o grau <strong>de</strong> eficiência em cerca <strong>de</strong> 10%. Por esta<br />

razão, o saquinho <strong>de</strong> amtra nitrat-reduct não<br />

<strong>de</strong>ve ser regenerado mais que três a quatro vezes.<br />

O produto amtra nitrat-reduct não é a<strong>de</strong>quado<br />

para ser aplicado em água salgada.<br />

Porém, o teor <strong>de</strong> nitrato da água da canalização<br />

po<strong>de</strong> ser reduzido com amtra nitrat-reduct antes<br />

<strong>de</strong> se trans<strong>for</strong>mar essa água em água salgada.<br />

Dimensões da embalagem:<br />

250 (500) ml no saquinho <strong>de</strong> re<strong>de</strong>, suficiente<br />

para um volume <strong>de</strong> até 125 (250) l <strong>de</strong> água<br />

<strong>de</strong> aquário, com uma carga <strong>de</strong> nitrato <strong>de</strong><br />

50 - 75 mg/l.<br />
