I keep my flow right at the point to where I get good turn over and nothing is staying stuck at bottom. that's why I like this design on the reactor. I use Eco bak by Warner marine, and of course I get it at elegant reef. so happy be gets it all in so I don't have to order over net.

kevin when ever you got questions just ask or call or text me. i am very happy with them and how they have helped keep nitrates down.
