After the head loss through 3/4" flexible tubing I'd guess I'm around 1000gph. I never measured it but everything is working well.
I have one on a upc and it reads about 70 watts. They may be less efficient, but they can be guaranteed to start every time. That can't be said by a DC pump. They are also a fraction of the price of a DC pump and run for years and years.
The DCs may be more efficient but after the initial cost of them, it is probably a wash.
I don't disagree with you. I think basically there are no DC pumps with a long enough track record to have a good comparison, we are going to need some early adopters to give them a try for awhile.
I am seriously looking at these new Sicce AC advanced pumps.... basically just a more efficient AC pump. That might be the best of both.
