I don't want to fruitlessly debate that "my dad is stronger than yours". LOL. Actually, I am more interested in learning about different pumps, their curves, costs, testing, etc. If my pump was not the best choice, I'll learn from it and thank the forum members for the lessons. At this point, the Hiblow seems like it would have been a better choice for my small pond if it is truly operating at such a low amp draw. The Gast does seem to have more capacity available at higher pressure requirements which I do not need, but the prices are comparable...

Journey, I think I see where WBuffet was headed with his comments. I would bet that the 100 watt spec is at the "Rated loading pressure" and that we could expect the watts to increase as the backpressure increased. I would love to see some test data to prove me right or wrong (or even somewhere in between). Enjoy your 4th!

Fish on!,
