Meet the new and improved (I hope) 4" diameter counter current protein skimmer. I'm hoping the bigger body will help with skimmate production. I also modified the output so that instead of it draining out of the bottom of the skimmer it will now go back up and over the baffle to the next sump chamber in hopes of being more efficient because of my sump design.
I built this in my parents garage so when I get home I'll cut the return and install a ball valve when I can be sure of the height of my baffle. Then I'll have dual control of water in and out of the skimmer.
Edit: Just seconds after install! Hoping to have good results tomorrow
