Remora on a closed loop

Thinking of using a WMD-20 Iwaki on my remora to get the PH out of the tank.

Anyone doing any closed loop skimming?
 
It's no longer a closed loop if you Tee it to the skimmer. Plus, skimmers work best when they receive tank surface skimmed water...
 
No Tee, suction in the tank, discharge into the skimmer.

Getting the pump outa the tank is my main reason.
 
So, you mean an external pump with the intake drilled/plumbed through the back of your tank?
 
So, where's the return to the tank going to happen? It's got to drain somewhere. Is this going to end up in the sump or something?
