It should be out pretty soon. I plan to call Monday morning and get some updates. At 4-5ft I approximate 500gph maximum flow. You can use 2 if you need to, the energy draw is quite low, we don't make this model pump, it is an Eden pump but we modify it to suit our needs and it has an acceptable quality and energy efficiency. Eden is a big Italian pump manufacturer, almost 50% of the pumps on the market under different brands are Eden pumps so they are pretty good and they build them to whatever specs you request so they have a nice heavy gauge cord and TUV approval.
