I think its a grat idea, although youre going to loose anywhere from 50-70% pressure or effectiveness from the pump due to the SCWD, if thats the route that youre thinking of going. I have one on my 15g and I love it! and your corals will too :) Just make sure you have a pump large enough and you'll be good to go.
