Well, I think I have narrowed the field, but want some more input.
128 gal. RR w/ 30 gal. sump. Which skimmer?
-Aqua C EV120 w/ Mag 5
-Berlin Classic w/ Mag 7
-Kent Nautilus w/ Mag 7
Try an E.T.S.S They are made near me and are IMO top of the line! Did you consider this brand?I have been told they are better than Berlin. I even saw a huge one at the local Marine Aquarium running a huge display tank! www.superskimmer.com
Go with the Berlin. I run a big Berlin on my Oceanic 200. You can't go wrong with those. They are pricy, but easy to clean, great to run... and they really remove a ton of s$$t.
