i was wondering if i could get some feedback on what chillers people have bought and like....i have a 90 gal tank and im worried about the water getting to warm this summer...i run an ac unit in that room however im currently hanging 175 and 400 watt mh lights...any advice is appreciated...

if its an open top tank you can try running a fan on one side and blowing across top of water , see how much it cools off your tank and then decide if you still need chiller. you will however have more evaporation (more topping off needed).
