Does anybody know if this is safe to use with nerite snails? I need to kill some planaria and this was a suggested treatment. (Yes Nick, I can use my no planaria but I really want to keep nerite snails in this tank! Lol.)
Assuming it is planaria.You could pull the Tetras out and put them in a bare bottom ten gallon, now I know you may transfer some of these " planaria " but thats not a problem if any appear you can treat the ten gallon with half doses of No Planaria.
Now as the Nerites can tolerate salt ( they need brackish water to reproduce ) you could treat that tank with slightly higher doses of salt.
