I got an established SW
tank a few weeks ago, and inside were several live snails along with some shells that haven't moved in quite awhile. I'm sure that there is nothing much alive inside, but I don't know if there is anything dead in there either. I would imagine not since they have been there since I got the tank and I assume longer. Should I remove them? I'm having some nitrate problems, big ones, but no ammonia or nitrite issues. I'm working on getting a DSB
in the tank as soon as I can find the sand, but I'd like to fix the nitrate problem without having to do daily water changes.
