Overflow gpm on a 90 gallon

[craigtaylor]

Does anybody know the approximate gpm of a corner overflow on a 90? It seems as though it has slowed down when compared to the flow of my mag 5 chiller pump that is choked back some, and I can't find anything in the piping like a snail.
Thanks

If memory serves it's around 800 gph.
What size chiller are you running? I had a 1/4hp inline on our old 90 and drove it off a Mag 3.
Also - check the pump itself sometimes gunk builds up around the impeller shaft.

give me a call today. if i remeber correctly you have a square over flow. you can pump alot more than they are rated for. i don't remember if you have a durso in there or not but i would think that you have an issue with the return pump due to the over flow will drain only what you ae putting to it. if there is no blockage tan it's the pump or some thing is in the intake side of the pump
