I've been meaning to get one for a couple years now and am looking to see if anyone has a 1/2 hp chiller or whatever size works for a total of 250 gallons. If you have an old one you're not using or want to trade some corals or just want cash let me know. On a college kid budget not trying to spend a whole lot, but want to save my corals! Text/call me @ (858)-997-4807. Thanks so much!
