1. Get an A/C unit to keep the room no hotting then 73f, the water temp should be close to the air temp.
2. Get a chiller this is the route I took. Found a 12 Gallon Chiller on ebay NEW for 150 + Shipping. It is working well. Chillers Model (CL-85)
3. Somethign i was looking into but the cost was clost or more for an ice probe thing that says it can cool 10 Gallon 10f. but you need teh temp controler and the cost is more then the chiller.
4. Cool tubes for your lighting (dont think it will work with your current setup but change the light and get a cool tube should lower the room temp alot.

Good luck. Check out my Grow as there are some notes to how iam fighting this root rot. Trust me avoid this problem at all cost. Only thing I have found to really Help is H2O2 switch can hurt the plant if to much and I have gave it alot slowing add more and more depending on how things look.
