hi all i managed to get my tank infested with vermited snails, got hundreds of little white shells all over the glass i see the webs popping up on the rocks. this is only a few months old system was thinking about taking it all down scrubbing everything clean but i'm sure there will be some in the rocks where i cant get to them. wondering if anyone knows how long i would need to let the rock set out dry to be safe that they are dead before setting the tank back up ?
