I've purchased all my plumbing parts and am about to assemble it.
I wanted to post my plans up here first though to see if there were any newbie mistakes I was making in the layout.
My sump tank sits on a shelf extending 6 inches out behind the back of the tank, so the plumbing can flow straight down into it.
One thing I was wondering about is should I put a 90 degree bend just below the overflow box then another 90 to turn it straight down, instead of just going straight down? I was thinking that might make it all run quieter.
The basic flow is to come out of the overflow box and down through a 1.5” drain pipe, with a Tee splitting off a bit of flow to go to the refugium (there is a hose barb there, and I’ll do a flexible 1” tube to get to the fuge, with a ball valve for flow control.), then it flows down, across the sump, and down again into the fill tank.
Also, how should I handle the piece of pipe in the fill tank? Should I perforate it with holes for drainage? Or just have it flow down and have the pipe terminate a few inches above the bottom? I was going to put a filter sock over the pipe to remove detritus.
For the return, I’m using a 900 GPH
Ehein 1262 return pump. It goes up to a 4 way junction, where I will have a drain line to the left (hose barb with a ball valve), a return line to the sump to the left (so I can reduce flow if needed to the tank without building up more head pressure) and then the return line coming out of the top to return to the tank.
The fuge will just overflow and drain back into the sump tank.
If anyone has any advice on things to change with this, I’d love to hear it. Thanks!
