pm bullet 2 skimmer - questions before setup

[robzilla]

i've got this unit up and running now, and have a few questions:
at times the foam is at the top and then most of the time it's half way up the large riser tube.
ive got the water set at 1 1/2" up the first large riser. the air valve at 5-5:30 as per the instructions.
does this sound normal??
any thoughts?

I can't keep my air valve open all the way though, the bubbles get too large and the skimmer burps and doesn't get good foam production. I have my air valve ever-so-slightly closed and it seems to create a more steady-state.

You'll have to find the right adjustment for yourself but basically with that interface line, up higher means a wetter foam, down lower means a drier dirtier foam.

I have to open my skimmer up once a week and wipe the mud out of it, the insides get a good 1cm layer of mud on the sides.

thanks tony, it's been trial and error but i'm following your advice and having the water level 1/2 way up. i'm finding good skimmate production.
thanks for the tips!!
