is skimmer OK ?

[stuartgiam]

I bought a second hand brekett turbo skimmer , used it for about one / half month . I noticed recently that the bubble count is not as much as the first day I installed the equipment in the tank.

Any thing wrong with it?

it needs some cleaning mate...

Could be something got clogged inside the beckett valve. Break it apart and clean it. Could be some piece of solid debris... tiny snails, pcs of sand/rock/algae/floss etc affecting the air/water mix.

Make sure your pump impeller isn't clogged either.
