Eric,
A few questions if you have the time.
1. What do you have your house set at?
2. Aside from heaters, what are you heat sources (lights, return pump, skimmer, wave makers etc....)
3. Is your tank and open top?
Reason I am asking is, I would like to not run a chiller. "Seeing" what components I could change out to have my tank run cooler.
Thanks in advance!
Robert
