I'm not sure how to exactly tell the turn over rate on my large tank. I have a 180G with 1 FX5 and a 30 gal sump, unfortunately the only info. on pump is "UL Model 7". Anyone hear of this Pump? It was used when I got it with the tank.
 
Do you have a picture of the pump ?

I do not have a pict. I will take it out of sump tonite and look again. It's black, steel housing, about 5" x 5", it will drain my 30gaL SUMP in a minute , when the overflow is disconnected.
 
Here's a thought, disconnect the overflow get a 5 gallon bucket ( make sure you actually measure 5 gallons and mark the bucket), turn on the pump and measure how many seconds it takes to fill 5 gallons. Devide that number into 3600 and multiply by 5 to get GPH.
This will give you a 0 head flow number and will help answer your original question.

It took 45 seconds, give or take a few. That was the sump. I'm also running a FX5
 
I'm tempted to ask if you did the math, but, 3600 devided by 45 = 80, times 5 = 400 GPH @ 0' head (give or take the number of seconds your original calculation may vary by) . What is the vertical distance between the outlet of the pump and the return outlet in the tank ? This will give us an idea of how much less the actual number will be.
We'll deal with the FX5 separately(that's the easy part).
 
UMMMMM.....

5 gal/45 seconds = 0.11 gal/s ; We know 3600 s = 1 hr ;)

(0.11gal/s) * (3600s/1hr) = about 400 gal/hr [seconds cross-out] :popcorn:

Calculator math :nilly:
