 Re: pump size to feed water into a recirculating protein skimmer
If I was purchasing, I'd recomend the 350. I believe that the contact time is important. The theory here is that the more even flow and the better the contact time, the more protein can be skimmed. Pushing water too fast will lessen the contact time.
I am reviewing your post and realizing that it is a recirc pump. 350 gph should be fine. The overflow is usually recomended since "most" overflows skim the surface of the tank where many of the DOC's are located. I would do all that I could to ensure the skimmer was close to where the water is entering the sump, the water level stays constant and as calm as possible for that area.
My tank turnover through the sump is only 400 gph for my 90I create flow through Tunze PH's and maxi mods.
So much for my soapbox speech.
I hope this information helps. Others may have differing opinions. |
