I bought a 65 gallon tank off of a friend. After about 3 months a found a snail in the tank. I didnt think anything of it. Ive always had fake plants so i didnt know anything about snails. A few days later my tank had snails everywhere. I've got a largemouth bass in the tank and they don't bother him, but they bother me. I don't want them to get stuck in my fliter and break it. I've heard the only way to get rid of them is completely drain the tank and wash everything with white vinegar. Is there anyway I can kill them and not hurt my bass without having to empty all my water. Please help.
