Hey guys Ive been working on this thought for a while. The dehumidifier Im looking at uses a heater to condense the water. In theory it should basically be just distilled water but something in me just says theres more going on that Im not thinking of. The reason Im trying to do this is cause Im putting my 180 (with 125 sump) and 60 gallon frag tank in a 10x10 room and if I dont control the humidity itll pretty much melt the dry wall hahaha. Let me know what yall think about fedding my ATO resevoir with a dehumidifier.
