Hang on Skimmers

[0sprey]

I don't know anything about the CNC...
But I have the Deltec MCE600, and I have to say... best damn skimmer I ever bought. Pulls more out of the tank than my in-sump turbofloter in the old system used to. Easy to install, exceptionally low maintenance, and it's very quiet. Even has a compartment for chemical filtration media!
Deltec is a good name. Failing that, another good choice is the Remora Pro... never used it personally, but it has good reviews.
