I have one of these suckers and I'm impressed with the quality of it but I'm having a devil of a time dialing it in.

The prinicipal detractor is the complete absence of any meaningful documentation on the product. For all intents and purposes, there isn't any ! No problem I say, this is a skimmer not a rocket ship; how hard can it be ?

Wellllll......pretty damned challenging !

If you connect it as it was designed (with the air hose connected directly to the collection cup) it immediately and continuously overflows the collection cup in less than 60 seconds. So much for that.

If you take the air valve that comes with the Maxijet 1200 and plug the air hose into that instead of the collection cup, then you can throttle it to a point where it won't overflow but it's very touchy. This is a fairly new setup so we'll have to see how it skims in the longer term but skimmate right now is very wet.

Microbubbles. Lots of them. If you connect the air hose to the collection cup, then the 'cloud' of bubbles are as shown in the picture above in this thread and nothing worth talking about ends up in the display tank (I should mention I have this skimmer installed in a DIY HOB sump). When I connect the air hose to the air valve instead, the cup no longer overflows but the 'cloud' grows dramatically and microbubbles pour out the bottom of the skimmer and into the display.

Arghhhhh !

Any help with this would be GREATLY appreciated.
