hey guys, well my tank is now mature to start a small clean up crew with a ph at 8.4 nitrates 0 nitrites 0 s.g. at 1.022 my problem is that i went to my lfs and looked for astrea, cerith (sp?) snails and they didnt have any (Do they have alternative names). They carry things like queen conch, red footed and turbo snails will these be alright? I only have a 9 gallon and I know that turbos get big. To be on the safe side i instead picked up a red hermit. Also i know the ideal s.g. for my tank is 1.023 and i was wondering how i could gradually raise it without killing any of my lr/hermit. Any suggestions to these questions would be appreciated
