Equipment

so I got a new skimmer last week and it was working ok But it was to deep in the water about 12 inches.
I got a stand built and know it sits at about 5.5 inches deep.

Manufature recomends 5-8 inches.

Could this be causing it to over flow?

I have it dialed all the way down both the air and the waterlevel. in the skimmer and its been over flowing for 24 hours st8 now

has anyone tryed these do they work I dont have space in my sump for biopelle reactor so If these work then its a great option for me.

Nitra-Guard Bio-Cubes from "orca labs"
