Im thinking of turning a small closet into a sump room. the closet is in my finshed basement and would have a 100g to 150g rubbermaid sump , and a small frag tank. and all my equipment. Im worried about mold an humidity problems. The door can stay open most of the time and there is no sheetrock just wood. The closet is aprox 6ftLx4ftwx7fth . Anything elsle I can do or paint over the wood to help with mold.I was going to do it in the room but it would be nicer in the closet out of the way.
