i hooked up the 12 inch cpr hang on fuge i got.
the extra pipe that it comes with i attached to the outake..since it is in my sump i wanted to submurge the outake(overflow) portion so it wouldnt make noise. I used the extending arm that came with it, but i may have it in the wrong spot? i will post a pic in a just a few minutes.
Anyway, Since it is in the sump i dont want a running waterfall, so if this piece is supposed to go on the inside, what can i attach to the outside to bring it down into the water? The pipe size is strange and i couldnt find anything at home depot. anyone?
the noise it is making is this sloshing/trickling water sound.
