You are only running 2 coral plus and 2 blue plus on a 10 bulb fixture, less than 50%. Those two bulbs (or similar) should be in the majority imo. I also don't like purple plus, too much red. Coral plus had enough red to eliminate them entirely, again imo. If I had a 10 bulb I personally would run:
4 B+, 4 C+, 2 Actinic.
You could then fine tune the blue/white with your kessils. Or you could use 5 B+, 3 C +, 2 Actinic if you prefer more blue and keep the kessils on 50/50. This would result in more shimmer than using say 50% blue/25% white to make the first combo more blue. The white from the kessils shimmers more than the blues.
Having said that, you could also use 6500k or aquablue special or any other whitish bulb in place of some or all coral plus if you prefer, I'd just stick with blue plus/white/6500k as your primary bulbs. Nothing wrong with throwing 2 actinic on a 10 bulb though.
Since you are not happy with several colors I wouldn't assume it's just the lighting though. If you wanna share some pics of the acros we could offer some suggestions if anything is obvious.
