skimmer bubble probs

[405ndn]

i have a aquamedic skimmer w a OR2700 pump. I put a valve on the pump b/c it seemed that it was too big for the type of skimmer i had. that seemed to have worked for a few days but my problem now is that it still makes bubbles but none of them are going up high enough to reach the top of the cup. do i need to increase flow to the skimmer via the valve? or should i put an air valve on the air line and reduce the amount of air it is receiving, and leave the valve alone? thanks for any help guys.

Increase water flow.

Is it a TurboFlotor 1000?

If so, there are two knobs on the exit tubes that control the flow thru the skimmer. I wouldn't try to slow down the pump itself.

I eventually tossed the knobs & adjusted via an air valve. Could never keep that p.o.s. adjusted for more than a day.
