Skimmer? air bubbles?

i have had my deltec apf600 up and running now for about two weeks and get rid of the skimmate every 3 to 4 days, but today when i did this, and turned the skimmer pump back on as i leave the pump that brings the water to the skimmer running, the air bubbles that run up the collection tube only went half way up, and it has stayed at this level since, so i have turned the pump off as i has making a kind of gurgling noise, do you guys have any ideas why it did this and what the problem is?

thanx again in advance,

andrew

some times it may take a while for the bubbles to rise. also, get some fresh RO water and let the skimmer suck it through the air intake pipe, because sometimes you can get salt creep restricting the flow. also, it is best to turn the litle valve off on the top of the air intake pipe rather than the air injection pump. this is because the pump will wear out quicker and they are very expensive to replace.
