thx for the info. i'm guessing hc-1000 is the way to go for me (coming in a week or so). i have not found a hailea 1500 anywhere.
also i was looking at some other manufacturers who offer more powerful chillers (aqua medic has a 3hp monstrousity) but the prices are just way out there.
i have one more Q though, the units are said to feature a titanium heat exchanger, does id play well with copper, aluminum, nickel, or i need anti corrosin stuff?
