I have a decent sized metal cattle stock tank (aprrox. 5' x 2' x 2.5'); I think it's made of either stainless or galvanized metal, most likely galvanized. Is it usable for keeping fish?
Oddball;3261529; said:A galvanized tank, especially a brand new one, will leech toxic levels of zinc into the fish's water. The zinc affects neurological processes that will cause symptoms of imbalance, ramming, gasping, aggressiveness, listlessness, etc.
An aged tank will still leech out chemicals until they're expended. Then the warm tropical temps will accellerate rusting of the steel base.
Better to line the tank with pond material or epoxy seal the entire tank inside and out.
