ds4x4 said:i've done the dehumidifier route even had a window AC down there. this was a 220DT with a 75g fuge and prob 75gals in a rubbermaid sump. best thing i did was open the windows and Bilco doors for natural air movement. all the Dehumidfier and AC did was run my electric bill up and they took a while to get the humidity under control
