Help water to warm 86 degrees

[coolmoon]

Help! I just set up my first marine tank, 65 gallon AGA overflow, reef sump rated at 75 gallons(11inches wide by 20inches long, 14 inches high). Lighting: 36 inch Coralife Lunar Aqualight with 196 watt 10k and 196 watt actinic.

My local fish store recommended that I put all my equipment inside the sump. The items I have: Super Skimmer 125, Mag 7 for the return, CAP 400 pump for the UV 9 watt turbo, and a stealth heater(set a 75 ). It was a puzzle but I was able to get it all in the sump. Right now I'm just running salt water, checking for leaks and adjusted water chemistry. With the lights off the temperature is at 84 degrees, with the lights on it is 86 degrees!

My question to anyone: are there too many items in the sump which would cause the temperature to rise to 86 degrees? If not, what else could be causing the high temperature?

Secondly, if I leave the equipment in the sump will it cause future maintenance problems as far as difficulty in cleaning the sump and collection of detrius.

Your advice would be very much appreciated.

What's your room temperature? Did you try unplugging the heater? You really shouldn't need it during the summer.

If you can afford a chiller, and the electric bill it adds, that would work like a charm.

If it was fresh, I'd say use a fan, but R/O water gets expensive... But it's still cheaper than a chiller, might be worth a shot.

I use a small blower fan I got from walmart for 15 bucks, cools the 75 gallon well enough, but I don't have 400 watts of lighting and all that hardware.


Everything with a motor adds heat, lighting more so.
Does it get any sunlight, direct or indirect?
Does the stand allow the sump to get fresh air?

Stick a termomitor under the stand, see what the ambient temp down there is, if it's warm, a fan moving fresh air might do the trick...

Update ..thank you all for the info the temp is at 80F to 81F with two fans during the middle of the day with lights on seems to be stable also I did discovered a rare problem on my mag 7 pump , I ran a hose line out side the sump to see if I could drop the temp before I drilled the sump,and turn it on water was leaking severly at the seal where the 4 screws held the casing ,opened it up to check it out and found there was no o-ring installed. based on the Mfg specs online ,took it back to the LFS (small advantage of buying local instead of online ) and they exchanged it and they said it was very rare, so I wonder if the pump was not being at full capacity had anything to do with temp , now I have everything in the sump again and and ready to move forward . once again thanks for the help.
