this is the chiller i bought for my tank and love it!!! I believe it is 1200 btu it is QUIET!! And within a month or two (if tims and i can make time to talk more) you will see an ariticle here in the FAQ on how to maintain this chiller
As you can see be the reviews on the site alone it is a great chiller good price range relieble!!
I strongly advise against getting this chiller you are looking at here the quality and specs just dont add up
sorry to say. This chiller that i linked you to have been proven to hold up in the long run you can ask Casey, Vinnie, Skeety, and few other reefers on this board. Also i have a 72 gallon tank with a 29 gallon sump......Price wise this chiller was cheaper than the one you listed.
I also use this pump to run the chiller http://www.marinedepot.com/md_viewIt...roduct=HG10570
