The only solution i ever found to cooling my tank (that worked for me) before i got my chiller was with fans. Now i guess you can use them in any way, shape or fashion but the air blowing across the surface cooled the temps down from 82F to around 76F. I too have the BC29 and the things are known to run
hot, but i have never had any problems with my reef being too
hot...just when i decided to turn the tank into a seahorse tank.
But i just took a "house" fan that was on a pole and placed it in from of the tank with the front and back lids opened for added circulation.
Now, im sure that you can probably come up with something just as effiecient and much less unsightly than my pole fan but you get the point. However i never had to install a fan on this tank so i wont be able to add in anything on how to do so without raising the hood someway. hopefully others that are more experienced will chime in soon.
