[sensei]

I have a BK 250 SM Skimmer in my 600g system.
I have around 30 fish, some of them large 10" or more and 8 tangs

I am having problems regulating my skimmer.
I am not sure if I am doing it well.

I regulated the foam to be around 1.5 inches from the top of the neck so that the neck does not get gunky and skimmer works well one week and then the foam level goes up and I get the cup full in one day and if I lower the foam after a couple of days the foan goes down more and gets all the neck gunky.
the pump idisplay is at 43 now.

please let me know what you think?

can you explain how to set up the pump correctly?
I do not know if I should lower the watts of the pump or increase them??

thanks a lot
