Okay - first, the low side of chillers I'd need are only about 450 (only, hah) -

So that answers that problem.
I've got my light a good 4" from the water surface. And it's a Double-Ended HQI bulb as well. Other than the fan, nothing was taking down the temp yesterday, until I turned off the MH...
As for the thermo - I used 2 different kinds. One from my salinity testing probe and one from a coralife electro thermometer. Both gave readings in the 80's - 80, 81, etc.
In the summer my first thought was to just get a small window A/C which I figured would solve the problem, but I know that means I need to keep IT running 24/7 - Surrey in July, yikes!!
Maybe we should just move to Antartica? =/
