I'm seeking help on a tank temp problem. I've got a 140 gal
tank, 30 gal
sump, 4x96 power compact lights, with an AmpMaster 3000 external pump. The tank has been up and running since 07/04. My tank temp consistently reads 82.0 - 84.9. First thing in the morning once the lights first come on I am over 81.5, even with room temp 70-74. While expensive, I think it's time to get a chiller. After reading other posts I have tried using a fan, but don't think that I'll be able to get the temp drop I need once the spring and summer temps arrive.
A few questions:
-Any pros/cons for drop-in chiller vs. in-line?
-With my set-up and limited space under the tank I don't think I can install an inline so that it truly is "inline". Just wondering if there is a way to recirculate the water out of the sump and then back in for return to the tank?
All comments and opinions are appreciated.
