Just tuned to see this thread is still going.
QA, I suppose I could take test readings, but my pond is at my vacation property and I won't be back there until July 4th. I expect them to reflect readings very close to what is advertised, as yours did though.
JF does a good job of connecting the power consumption to actual cost.
For the purpose of passing on info I have learned that I consider valuable I'll summarize;
The HIblow 120LL is about half the cost of the Gast 0523, and uses less than a quarter of the cost per month to operate.
By the way my vacation neighbor just purchased the same pump I have and is quite pleased, as am I.
