I'm trying to rid my small 10ga tank of a snail infestation. I bought a product from the LFS (basically copper sulfate solution, 1g/L) and have followed the directions (10ml per 10ga, repeat after 3 days).
I'm not sure what to do after all the snails are dead... the bottle says that copper sulfate is toxic to fish in soft water (the tank water is soft) so how should I prepare the tank for fish? Perform a whole lot of water changes? Like 75% 3 times, or 25% 5 times, or what? Obviously (being a former chemist!) It will be impossible to remove it all, I just wanna make sure it will be safe for when I restock the tank.
