Yeah.. your params all look fine. Some other things to check:
Salinity -- if you haven't already, use another method to measure your salinity.
Bulbs? -- maybe the bulbs could use replacing. Have you ever measured your PAR?
Fish -- Could you use some more? I have a really messy blue tang and moorish idol that crap whenever they see a bubble. The acros love the crap.
Light intensity/spectrum -- How long do you keep all T5s on? Which lights do you use?
Carbon -- if you're not running it, definitely do; removes anything bad that might be in the water
Maybe iodine or strontium deficiency but if you're doing water changes once in awhile you should be good.
Or maybe you're right and you just need to drop the nitrates. There's some weird chemistry going on in our tanks and what works for one reefer doesn't always work for others (dirty water) . Good luck John!
Man I don't know anymore. We're all been told high nitrate &po4 are not very helpful when it comes to colors but these days I keep hearing/seeing nice tank with off the chart phosphate .1+ and nitrate anywhere from 10-20ppm...sigh
check the source??? the internet allows for "some" exaggeration! any book, reef i've seen, personal experience, or coral expert will all lead to the same advice: feed your fish and keep no3 and po4 as low as possible.

Others on clay-boa reported the same outcomes. But what am I to say I'm nothing but an average reefer that can keep corals alive but not the colors I wanted.
Something doesn't add up. With what you've described as your fish load and feeding you should have very low po4 and nitrate. It's almost like you have no bacteria.
1. How long has your tank been setup and do you have coraline algae in your tank.
2. What are you using for circulation?
I know, right? It's a 10 months old system with some coralline, just here and there. Is coralline an indication of success? I, too, suspect lack of bacteria but how could you tell?
Great looking MI. Care to give me a crash course how to keep one? Did you QT yours? How long have you had it for? Thanks
