We got skim, checked today and sure enuf i learned how to fine tune this baby.
Sure its meant for 900 gallons but there is no reason it wont do a better job on a smaller tank.
Added ozone myself with a nozzle from an old air stone.
And the drain line from the skimmer goes right under my cube into a siliconed hole around the skim drain hose, and a siliconed 2 liter bottle in the center of the bucket filled to the top with carbon.
This is done to strip the ozone from the air before it becomes hazardous to my heath, in my smaller apartment it doesn't take long for my eyes to start to burn and my throat get all sore. But the payoff so far in the last 30 days for the pros far out way the cons.
I plumbed the skimmer to be a central point and easy to adjust, basically u cannot look at the reef without seeing the skimmer.
The skimmer drain is a design by accident.
I placed a T on top of my cubes drain pipe to start a durso style overflow since i was passing alot more water into the cube to quiet things down some.
The level of this pipe before i shortened it from the skimmers out flow was just about the same so i made it fit into the top where the air vent hole should go.
A full 1.5 inch air//water mix, then the durso heads elbow into the water.
Thats about all i have on the skimmer, next some non detailed pics of the cube.
