I am just about finished with my new QT, It is using a 6' DreamPond show tank with a 55 gallon settling chamber and 55 gallon moving bed filter. I am running it with a 500GPH mag drive pump for now untill I get a pump for it next week. The filters will be built in to look like the fence and remain in place so all I have to do is get the show tank out hook up a couple ferncos and fill it up. It will be heated with a coil of composite tubing installed in the bottom of the moving bed filter from a flat plate heat exchanger that I heat my main pond with. Next year I will be building a 2000 gallon pond recessed into the deck.
