Ok, well, a little background then... When we moved here 4 years ago, we setup a reef tank. Using MH
lights, we of course needed a chiller. Wife and I getting older, changing life styles, we sold all the reef critters and went with the current FOWLR
. No more MH
lights, but still T5's, actinic and white.
We had the chiller set at 75 during reef and fish. With the fish only the chiller didn't really seem to have to work too hard/often. Sometime Friday the chiller crapped. At least I'm assuming it crapped because Friday night the temp was 80 degrees.
Lights have been off all weekend, the tanks is staying around 76, the temp in the house is currently 71 and has been for several days. Don't need to run the house heater or the AC
this time of year - yet.
In an hour or so when the wife gets up, I'm going to turn off the chiller. I'm actually thinking it's dysfunction may be causing heat.
Short answer? I dunno
How warm is safe?
