I just used it as is. It's about an inch off the substrate. Not sure if these things are supposed to be a certain length. It works good but I get a lot of micro bubbles even with a big chunk of sponge in the bottom. I'll mess with it a little bit more then I'll go back to my Rex Reactor since it was bubble free. Because of this setup I was able to remove a big clunky powerhead but I think I may add another Koralia nano that I have to move water directly past this reactor to get the CO2 across the tank.
