SteveC, flow rate on this larger unit is 10,000 l/hr. You guys not on the metric system do the math. It's made in Europe shipped to the only distributor in the USA, Purdin Koi in Baton Rouge, sold by a few dealers here.
The Clarity is NOTcheap but worth it imo if you want the best water. Retails for almost $2k here.

Don, i hope to set mine up soon but don't want it sitting next to the pond, the thing looks like a vacuum cleaner. I want to see how you're doing yours. Will you gravity feed it back to the pond?
