I’d increase the white to 25%. This is a change I could make on my 24 gallon cube with 2 AI Prime HDs, at once single adjustment and not have any adverse effects on the corals. SPS does like a little flow. Just make sure you’re not blasting one that may be in close proximity to the powerheads. You could rip the flesh and kill it. With SPS, you probably need a little more flow than you have, but it still affords you to have a flow that blows it at an intensity that you appreciate. So if it were me, I’d do the two adjustments the same day same time. But maybe do flow increases in 3 segments instead of the one time increase that is likely ok with those lights. I’m not a know it all. Your tank is searching for what it likes. And every tank is different. You have a beautiful setup and you seem pretty close to what it wants. Just haven’t nailed it on the head yet. Good luck with it and if you could, continue to post progress pics on this thread so we get notified and can watch the project. It going to be a looker when you hit it on the head. And I’d like to see the finished product if possible. Good luck man.
