I'm looking for some ideas on how to cool the water here. 5 Gallon bucket with 3 gallons of water in it. Aeroponic delivery. I dont have a thermometer (low budget DIY project), my guess is that the water is between 80-90F degrees.

I read in some other threads where u guys say warmer water doesn't hold much oxygen, but in this setup the roots are suspended in air/hydroton and being sprayed by water so is the water temp even much of a factor in this case?

Some pics to help below.:thumbsup:
Other variables:
-5 CFL's 3 cool/2warm all 40w (roughly 8-9000 lumens total)
-room temperature floats around 85-90 during day, 75-80 at night
-Hydroton rocks for medium
-Tap water - PH'd around 5.5 - 6.5
-1 large Computer fan inside moving air around plants
-submersed water pump - 100gph <-- is this producing the heat???

Thanks!
