Hey guys-
I have the RS135 and I ran it for a few days with RO/DI water when I was testing my plumbing.Today I turned it on and added my base rock and everything including my drain line foamed like crazy. The discharge pipe on the skimmer is blowing tons of bubbles back into my fuge. Something doesn't seem quite right. Here are some shots.
The discharge tube.
The collection cup.
The skimmer washing machine chamber.
I have the air tube turned down a little so the foam doesn't blow the top off the skimmer. The discharge is set to fully open. It is sitting in 8" of water wich is OK per the manual. The instructions are a little lacking on dialing it in.
