Chris have you thought of wavemakers? Not sure if that will solve the problem, but paired with your ph's it might create a good flow all around...
(Thinking Tunze Turbelle, Korallia, Vortech, etc.)
In your current 140, do they yellow tangs get along?
Chris I am not sure I follow your concern. Flow will always occur towards the return overflow slots even in as wide a tank as yours. So as long as you have enough flow below the surface to keep your corals happy, I would think that you will always be getting the surface water of the whole tank into the returns...
Nice setup. Will be following.![]()
Oh man, I love Emperor Angels...I think they are one of the prettiest angels around. One day when I have my large SPS tank I will have angels as well.![]()
