Increasing bubble production in skimmer

[soriano]

Delphinus, thanks for the info. I'm going to double check to make sure those no blockage. I don't think there is though. The skimmer is new and from the time I set it up, i wasn't too thrilled about the bubble production. The bubbles produced don't look anything like some skimmers i've seen (where you see a huge swirling white cloud).

As for the pump, i think it's adequate enough. I actually have to turn it down otherwise water overflows into the collection cup.

Actually that's another question.....
How far should i let the water rise?

a) base of inverted funel neck leading to collection cup
or
b) about an inch from center reaction chamber

(hope that was clear)
