90 gallon display, 40 gallon sump (well... probably only 25 gallons of water though)
Mag950 return pump
Reef Oct skimmer with a OTP-3000 (40W) pump
2x Koralia 1500 powerheads
2x 108W LED
fixtures (with fans, well ventilated)
With everything running, the water temp goes to 84F degrees !!!
So I've got the skimmer off, and the temp is dropping. At the very least, that'll have to go on a timer and only run part-time... but the plan is to put corals in this tank, so I really need to be able to control the temp with the skimmer running full-time.
I may put a small fan in the hood and see what help I can get from evaporative cooling, otherwise it seems a chiller may be in my future.
Any other ideas for keeping it cool? (Before I pop $500 on a chiller.)
(Yes, this is a brand new set-up ... a few fish have been in for less than a week now after cycling the system ... meaning it's not a new problem in a previously stable tank, but an ongoing effort to stabilize a new tank.)
