So I'm curious to if any of you have issues in there fish room. I'm talking if you're running several tanks not just one big one. All my tanks are in a basement that is just block wall not really finished . Humidity really gets up there in the warmer months I have a dehumidifier really not strong enough also in the past few years got one of those portable ac units that exhaust out a window this helps a lot but still would not mind something stronger . What are others doing?
