Skimmers add quite a lot to evaporation too. I just hooked up my sump and skimmer, and I now have 2 degrees warmer, and just under 1 gallon per day evaporation. I have a Poseidon pump though, and they are notorious for adding heat since they are water-cooled, not fan cooled.

Ummmm the 400Watts of light over top has a huge effect....if you put fans blowing through your reflector across the bulbs will help keep that heat away from the water!!!!

When I finish my new stand project it will have two of these fans.
http://ncix.com/products/index.php?s...ufacture=Gelid Solutions Ltd. I read about them here on canreef, another member is using them as well. They have a thermal remote switch. From what I can remember the fan turns on at 22 deg at 1000rpm and ramps up from there to a max of 1500 rpm 12V, 58CFM, 12-25.5 dBA Hopefully they will keep my cabinet cool Edit: Paste this complete line as it reads into your browser http://ncix.com/products/index.php?s...ufacture=Gelid Solutions Ltd.

OK, for the last 2 days, I have been running the tank 0 lights. Just the 2 External pumps. No heaters either, and it's STILL running 80* Checked the thermo in my other tank, within a degree. Unplug the Little Giant 4 and temp drops to 79 after a few hrs.
Just WOW, there's no real head restriction in both pumps, and no water to motor contact. They are both external pumps, air cooled. But yet they ARE adding alot of heat. I'm baffled how that much heat can be entering the tank. House is kept 70/day 65/night

Have you checked the ambient tempature inside the cabinets? Since you said you have to keep the 150's cabinet door open a bit it sounds like you need more air flow through the cabinets. You could check it by just keeping the doors open for a day.
