mark and marley I sometimes write something and then sit on it for a bit before I hit post. Sometimes I don't. I try to sit on the fence, I have the tanks posted and 3 enclosures and a rack so a little bit of everything. I don't believe and one is better or worse just different. People will jump on tanks just as quickly as people jump on tubs. It isn't what you set up it is how you set up the enclosure that matters! Careful, attentive and diligent beats lax, lazy and negligent.
