There was no foam for the first week I ran everything. The skimmer ran but didn't pull anything out since the system was clean. Then I added the base rock without washing some of it and "bam".....foam city.
I took the water exit pipe off so it's not exiting underwater and that seems to have helped. You can see it exiting here.
I have the water level higher in the body and it seems to be working better considering there is still some foam left in the sump.
Having someone on the board has been a great help!
