Usage for hash tag: PP3MDQ

...recirculation skimmers (Meaning they have 2 pumps, one to feed, one to power the Air Fractionation) The MTC skimmer I have was a pretty easy rebuild. I rebuilt the MTC Power Pro Model #PP3MDQ skimmer, details are in my Build Thread. I added a second Mazzei Venturi to mine when I replumbed it.
