Reefers,

I have a external recirculating skimmer, when I bought it I read great review about it and tech gurus told me that was the way to go. The skimmer did a decent job but I was not greatly impressed, however I tried to keep making adjustments. Finally after 3yrs I got to the adjustment and changes that makes my skimmer rock.

So the questions:

Do you know if your skimmer is at its optimal performance?

How long did it take you to fine tune your skimmer to the point that you are happy?

What is an indication that your skimmer is not doing its job?
