or artificial sea salts preferred;
seawater is normally 30-35 g/L; use
non-iodized table/rock salts; some
anticaking agents in solar salts are
highly toxic; species sensitivity is
highly variable (some catfish
sensitive); may be toxic to plants

Gastric nematodes; anorexia may be
seen (more severe at higher doses),
generally resolves within 2-4 days
Trichlorfon (dimethyl
phosphonate)
— Caution: organophosphate,
neurotoxic, avoid inhalation and
skin contact; aerate water well;
especially toxic to larval fish, some

silver dollars); other species

treatments for Dactylogyrus and
other oviparous monogeneans;
treat q7d×4 treatments for anchor
worms (Lernaea) and fish louse
(Argulus); single treatment will
usually suffice for other copepods,
