ok after speaking with dave spencer yesterday at the green machine ive decided to re use the as that i have. its only a few months old as is perfectly good. my question is after emptying the tank of water fish and plants im going to have a "dry tank" so to speak. while i rescape. will the damp AS fester? how long would i have before things start to get smelly? bare in mind i want to arrange the stones over a period of 2 weeks or so, so i can analyse
