So, the REAL question is how to tell which pump to buy?!!!

What are the critical factors someone needs to consider when looking at manuf. specs. All that they have is head, flow, (max) input power?

If I specify that I will have 200g/h flow.

Then can I just look for head vs power @ 200g/h?

And find the highest head with lowest power?

It would help if I knew how much head I needed. I guess I'm going to have to break open the system and measure it.

I know that this is over-simplifying things a lot, but isn't that what others will really want to know. (other than those of us who enjoy the physics side of things)
