I am running a 60 gal display tank (30inch length) with a 10" glass thickness. I am currently using a Vectra S2 and one MP40, which is rated for 50gal - 500gal. When I introduced my pair of clownfish they seemed to be carried away by the MP40, which at that time I had the reef crest mode at 40% intensity. They are swimming only at the front of the glass, so it just might be the place where they like to swim at the moment, but I am also wondered if it could be too much flow for them from the MP40. I have dialed down the intensity to 20%, but wanted to see what you think the intensity should be from the MP40 for this tank?
