i have two 300 gal tubs in my basement in area that is 16'x12' and i am running a basic house dehumidifier humidity is 70% dehumidifier is running non stop. i am running a fan to circulate air and the tubs even have tops. any suggestions to lowering the humidity. it feels like a Sonia and i have only one tub heated so far so i am sure the humidity will increase when i heat the other tub. any suggestions?
