Freaky:
Thanks for the input.
Well, there are lots of pumps out there that seem like they would be ok according to specs. The one thing right now that I'm not sure how to tell from spec or otherwise is how low the GPH rating will fall once it's put into a W/C system with all the restrictions in the water line.
One of my other candidates is the Eheim 1050. But I'm not even sure of this pump's ability to handle restrictive loading and backpressure. The Eheim seems to meet criteria 2-4 no problem though.
What I'm looking for again:
1. Sustained 250 GPH even when restricted.
2. Small enough to fit in a case easily.
3. VERY quiet. Less than 30db if possible.
4. Low heat production #'s.
As for #1, I'm not entirely sure if the head hight rating of the pump is what tells us what happens to the GPH rating. It might only be PART of the equation. I'll find out soon though. I'm going to try and contact some knoledgable people on this topic and I'll post the info.
