asm skimmer

[hqgc]

I've had my G2 for about three months now. It is in about 8 inches of water and seems to be working fine. I have mine set so the water level is about a third of the way up into the collection cup. The adjustable part you are talking about is just the elbow so you can move your pump where you want.
I have been trying to do the gate valve mod but have had no luck finding a gate valve (Edmonton).
There is an excellent asm skimmer faq of RC but I can't seem to find the link.....
