Great to hear that it is working for you now.
10 holes. Right, I'll have to remember that.
As for ?'s I do have a few right now. With alot more to come in the future I am sure.

ops:
Are you using a ball valve or a gate valve? If it is a ball valve did you have any problem adjusting the waterflow with it. I keep hearing people say that the gate valve is better, because, it is easier to make adjustments. I would rather use a ball valve if it will work, because it is less money and easier to find.
Are you running it in sump or out? I was hoping to run mine out of sump and just attach the skimmer output to a bulkhead in the side of the sump. I'm not sure what effect if any the water level in the sump will have on the skimmers performance or output. Any thoughts on this?
Thanks.
Oh, just thought of one more ? Did you use cast or extruded acrylic tube?
