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.
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.dawnmarie;4018177; said:Do you have a picture of the pump ?
dawnmarie;4018264; said: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.
