i'm very happy with the PA-50 system , no problems yet , been running about year now. i ran 220v about 700 ft to 10 ft from the pond , installed pump on concrete , used the fake rock as a template , poured the concrete about 4" on the ground with old formica as forms , stops the rock from blowing away . the tabs suck , very easy to check things. i'm running it 6 hrs a day , 3 times. it ran the bill up about 7 or 8 $ a month , thats a 1/4 hp unit. 115 or 220 uses the same power. the pond has never looked this good. i'm sure the fish are happy lol \:\)

i only wanted to have some fun
