I’m try to run an SPS dominant mixed reef in a reefer 425 (4ft long 90 gal). My tank is young with just a few frags for now. I started off with 2 MP40s on the back wall and then added 2 of the larger gyres that I placed vertically along each over flow and pointed towards the back corners. I added another smaller gyre on one of the side walls. I’m currently running the larger gyres at 30%, the MP40s on reef crest at 40% and the smaller side gyre on 80%. How do I know if I have too much flow or too little? Is it possible to have too much?
How much flow is too much?

As long as you don’t blast the direct flow right at the frags, you’re fine. I have 2 MP40s and 2 WAVs all running 90% at their peak, granted my tank is full. What you have now is more than enough and yes, the more [flow] the merrier!
