After looking at your tank more carefully, I was wondering... how the hell does that skimmer work? Is there a method to the madness or was it just dumb luck?
I ask because i'm planning a new tank with herbie pipes and was thinking a little extra skimming never hurt nobody.
Well I noticed that when I closed off one of the herbie pipes the safety pipe spewed tons of bubbles. This just led me to start thinking of a way to collect the bubbles and somehow reducing the amount of bubbles released into the sump. Given that my tank sits around 3 to 4 feet up, I was hoping the reaction time for the air and water would be sufficient.
I first beta tested the design using a styrofoam cup (was heckled by ADIN to) as my initial fitting for my collection cup. The original design was much more complicated. I had initially forced the water to go through a few twists before outputing to increase "reaction" time but opted for the easier method, which turned out fine. It's really easy to do! Just get the fittings from home depot, and sit them on top of a u-pipe, add a collection cup and see if it starts skimming! You can adjust the amount of bubbles by increasing and decreasing the flow from the ball valve on the main herbie down pipe. Just make sure that the pump will not over power your safety pipe.
