Anybody Know...

How many gallons per hour I'm pumping?
I don't have my literature:
50 gal long: Fluval 304 (260 gph), Powerhead 301, Modified Skilter Supreme 250, 3 Small Rio (50) powerheads.
Is this good enough (for now)?

I don't know the numbers for those devices, but I think what you need is good water movement. If you have no stagnant areas, and your corals are swaying in the currents, you have a good start. I also like to see heavy action at the surface to increase gas exchange and aid cooling. If your pumps accomplish these things, the numbers are no big deal. If you have the right numbers and don't accomplish these things, it is still lacking.

Sandy,
Estimations of what you have assuming all equipment pumping at manufacturer's maximum ratings with clean media - no restrictions.
Fluval 304 (260 gph)
Powerhead 301 (174 gph)
Skilter Supreme 250 (250gph)
3 Small Rio 50's each at 69gph = (207gph)
Total: 891 gallons per hour
17.82 turns per hour
More than sufficient water movement/circulation for a 50 gallon long tank - in my opinion

lol, broomer, you are the man!!!
i thought i was the only one who posted specs that good, but you beat me by going so far as to give the exact turn over(i would have only estimated 16 or 18 times per hour)

LOL fshhub !
I guess that does look pretty silly ...
Estimating down to the 1/100th of a turn per hour
Oh well .... such is life when you are calculator dependent <img src="graemlins//urrr.gif" border="0" alt="[urrr]" />

Wow. Thanks! I *thought* ya'll would know .
And yes, good water movement on the top breaking the surface some. Fluval output and Powerhead 301 at top. Skilter output also.
Two Rio's in back bottom behind rock and one Rio front mid range with gentle flow toward rock that likes to grow red algae.
