The skimmer is working fine, although Im not sure as to why you have foam on
the surface of your tank, but it would appear its doing it's job

hi,

My skimmer is producing foam and brownish/greenish liquid in the cup.

However, occasionally I get some little Islands of foam floating on the
surface of my tank.

I have a Remora Skimmer---should I adjust it in some way?

thanks again--------------------
