Man! These things rock!!!!!!!!!!
I am waiting on my mazzei injector still so I decided to run it as is until then. I am using the built in injector right now and decided to try it with a rio 3100 pump for starters. Within the first half hour it started pulling dark crap out. I used an o-ring on the exhaust tube to set the water height in the skimmer and I also used a special air valve I had laying around to adjust the airtube. It is great as is!!!!!
Makes nice fine bubbles with the pump at full throttle.
Man did I get a deal, and what is even cooler is that I was smart enough to order two of them! I have never spent better money on my tank than this. To think I could have spend 400 bucks to get something comparable...
I am ordering a needle wheel pump also to try and we'll see what's better. That or the injector.
It is also pretty decent as far as quality goes. I played with it for about 15 minutes out of the box and had it up and running easily.
For a skimmer that is not ready to run out of the box it sure was easy to get running with parts I had laying around.
All I can say is that if you don't capitalize on this deal, you're a fool!
