Just wanted to give a little update. I am totally amazed by my Octo NW200 skimmer. I ran the skimmer without any mods for the 1st 2 weeks to let it break in. Then I started tweaking it. There are tons of pics and threads on RC about modding these skimmers. All I can say is you will not find a better skimmer for $200. This thing is great and I'm not done modding yet.
Just for some reference, the skimmer body is 8" diameter and is sitting in my 55g sump. I marked the line where the water ends and bubbles start. I like to skim dry.
This is about 2 days of skimmate (8" diamater cup). YUMMMMY
Yep......$200 for this skimmer. Octo also makes 2 smaller versions, and of course, bigger ones too.
