I just had the pendant modified by closing in the end as you suggested. I have not been able to run it for a full day yet. Today will be the first full day. I am still running the old AB bulb. I sent the Venki bulb to him last Wednesday by expresspost, so I can only wait. BTW I am getting some flickering from the light. Quickgrow said that is common, and I should make sure the bulb is screwed in tight. I did that but it still flickers. Any ideas :question:

I also have just gotten a new skimmer and I have had lots of bubbles at first, I have now ran it for a few days and al was well, almost none, but last night (although after a water change) noticed bubbles again and nothing moving into my collection cup.

Not really any help but I guess I am saying that it can happen here and there, talking to others it goes away after the break in period.

After a couple days it has settled down now. Thanks for the help. :)
