Thanks guys! TDevil...yes, we have considered attaching it to the wall. In fact, I think hubby has that all planned. I am going to have locks on all cabinets, so the kids (including hubby

) can't get into it. Even if my daughter knows better, her friends may not, and I don't want to find them tasting skimmate, playing in the sump, or worse. I will also have a stool near by, as there is no way I'm going to be able to work on the tank without one, so she will probably have her own stool to see what's going on inside.
