Best Chiller for a 75-gallon system

[Anonymous]

I need a temp drop of at least 10 degrees on a 75-gallon set up (45-gallon tank, 30-gallon sump). I have AC, but can't afford to keep the whole place frigid all summer for one system.

I'm usually a searcher: I actually use the search feature on these boards instead of asking questions that have been addressed a hundred times. BUT, I'm getting tired of wading through hundreds of irrelevant (to me, anyway) hits, so does anyone have a suggestion? I'd love your suggestion to be the least expensive one on the market, but I have a feeling it will be just the opposite.

Whatever is best for my system, I'll bite the bullet and get the best I can afford.

Hmm I dunno but make sure it doesnt have to run non stop just to keep up with the temps your after...

I've used various chillers and love the Aqua Logic units. My current AL has been running a decade without problems. But be aware no conventional chiller runs silent and they all emit a lot of heat into the room, so unless you have a basement or can plumb it outdoors, it's still best to use AC. Unfortunately, you'll need these type of conventional compressor chillers for a tank your size (for a 10 degree pull down). You can't get away with peltier type chillers. All of these are in the neighborhood of $500-700 last I checked :?

Evaporative cooling, of course, is cheapest but 10 degrees is a lot to drop with that method
