I wanted to add that my MTS, Ramshorns, and pond snails don't seem to have any problem with it. My Briggs were hiding in their shells tho.
:welcome: to AC!i was wondering if you are able to put chemicals in while the fish are in the tank ecause my tank is looking a bit dirty and i think that i might have ti add some. and also when i do a water change should i also add the chemicals to that to because i am taking it out and replacing it with new?
