    Does anyone have any experience with 1/2 hp water chillers?

    chillers did not work for me, so what im going to try is take a 7.0 (52 gallons) cubic foot chest freezer seal the inside with RTV and put a thermostat on it and set the compressor to come on @ 68 F. and off @ 58 F. if you want to use a chiller you have to insulate hell out of your res.
