9' x 18' 3,800 gal. partially inground concrete block pool. Only 4.5 feet deep. This was a DIY koi pond we converted with a custom liner and added returns. We reused the pond skimmer—a Savio Standard Skimmer—and it is working just fine. We are using a 1 HP Pentair Dynamo pump (two speeds), Black Diamond 90 filter, and a Raypak E3T 11KW 37,534 BTU Digital Pool and Spa Heater. My K-2006 Test Kit helps to keep it crystal clear with liquid chlorine only.
