de-humidifiers

[rossb]

In my basement I have an open 100 ish gallon pond, a 90 gallon tank and now a 180 gallon tank. The water circulates through a big filter and falls back into the system. Above the tank I have a 1000W Mh light, and the floor has radiant heating. I am planning on adding another 500 W of lights this month. Already my windows are dripping. You can easily detect the humidty when you desend ino my basement. I add 3 gallons of water most days to the system (some is used to water plants ... which I have in abundance).

I would really like to get a plan for one and would be interested in manufacturing one. Anyone else interested? Anyone have a plan?
