Holy smokes (talk about coincidence), my wife just told me today she was calling the exterminator for carpenter ants. I have a 10 gallon nano (lucky me) and will be moving the whole tank for a few days. I don't want to, but if they want my infant daughter out for 24 hrs (10 hrs for adults), then it's not feeling like a good place for my fish.
I've checked out RC and Nano-Reef, and in similar situations, people have tented and vented (outside air), sealing with plastic, duct tape etc... Contemplated it for a few moments, but we're talking about a 10 gal. tank here... seems like a no brainer (in my situation, not yours unfortunately) to move the tank. It's going to be a tough call.
