![]() Nice lookin cab
I think it was Brad who suggested before that you don't restrict either of your drains. If one gets plugged you may have a bad experience I'd suggest you run both your drains wide open and use a small pump to feed the 'fuge |

![]() yeah i concur about both drains wide open. i don't understand the need for yet another pump for the refuge though, if it's receiving overflow water on a steady basis and draining into the skimmer dept., shouldn't that be ok???

![]() It'll all depend on the design of your sump

![]() it's designed so 50% of the overflow runs to the refuge directly, (after baffling)
the other 50% runs to the skimmer chamber the refuge overflows to the skimmer chamber so basically the skimmer chamber is experiencing 100% of the flow. It's the last in line before the return pump. All of the water passes by the skimmer but only half of it passes thru the refuge. Initially I thought I would dial down the flow to the refugium and have most of it go to the skimmer chamber, but then I realized that with the size of the pump I plan on having, I can't afford to restrict any of the flow in either pipe. So it's a 50/50 split. |

![]() Sorry, I had a thought I didn't write
![]() Slower flow through your 'fuge is better I was thinking about you running both your drains to your skimmer section, then use a small pump to feed the 'fuge. This way you can regulate the flow if it's too much. It's possible the amount you'll get with your current design will be acceptable, but you might have to experiment a bit |

![]() ah that makes much more sense. lol!
i have also been experiencing some doubt that the flow rate is slow enough through the refuge. I guess I could direct both drains to the skimmer chamber and either use a small pump like you said, or possibly tee off one of the drains into the refuge. i suppose it's best to use freshly skimmed water for the refuge, but i also want to use fewer pumps. i'd hate to see a siphon form from the refuge to the skimmer chamber, because if you combine that with back flow from the tank, they could add up to a flood. the refuge and pre-fuge chamber carry more volume than the skimmer and return pump chamber. |

![]() A Tee would be a better idea for cost savings. Only thing I'd suggest is you open the valve fully periodically to flush out whatever may be stuck or building up inside it
Using non-skimmed water is better for your 'fuge, so your Tee wins there too |
