Thanks for that pHaestus, I think your results fall within BillAs, if one look pretty close up...
What do you think about adding a bypass to the rad?
Ya'll know that we talked about pump efficiency, but we didn't say the words: if you're shooting for high GPH, you should get a higher pressure rated pump, so that the pump runs in an efficient range. What I'm having an issue with is that there are few, if any centrifugal pumps that seem to have those specs, so maybe we should review the whole big pump thing, and start looking at other pump types.
The Eheim 1250 is not all that great for pressure, but no one questions it, and since Eheim won't put out P-Q curves for them, then this thing starts falling the way of the rumors with statements like "get an Eheim, it's the best". Shame!
