I’ll be attempting a primarily SPS tank on this one so definitely will be needing a lot of flow. I’ve read that the wave box can have some negative affects on tank structure and could potentially shorten the tanks life span which is the only thing I’m afraid of.What corals are you going to keep? With the pumps being adjustable you can start slow and bump them up as needed.
Think you'll be fine with what you have. Can always add more down the road if needed. Or move them around on the back glass to get the flow where its needed.
