Let me know if all looks good. Compared to the MJ 1200 running my diy scrubber the Rio is a beast!! Water flow was very noisy at first because I had it at full blast no valve. I ended up putting in the ball valve and dialing the pump back a hair. Then I closed closed the flapper drain almost as far as it would go. No noise now and the water level in the growth chamber is just below the false bottom. I imagine once the screen matures I will be able to crank the flow up all the way. That's how my diy scrubber was. I used egg crate as a temp support. I have an idea for something more permanent but that's for another day. Turbo Aquatics L2 Scrubber
