The thing I cant see working would be that both sides would have water overflowing through the skimmer holes.
Also, how would I incorperate a sock filter in the sump?

That could mostly work. You would lose the surface skimming action from the 2" box.
You put a standpipe on the 2", emergency, overflow. Make it just, just higher than the operating water level in your display tank. That box should then fill right up to tank level.
Then put a gate valve on the 1.5" overflow and dial it back until you have a stable water level in that overflow box. (don't put a standpipe on this drain).
As you should have 100% of the flow going through the 1.5" gate valve'd drain, you can have that water drop through a filter sock if you like. Have this pipe exit below the surface of the sump. Your filter sock would therefore be submerged as well.
Of course, once you have all that running...try shutting off the gate valve and see what happens! All the water should immediately begin to fall down the 2" emergency which should create enough noise to alert you that the system needs attention. |
