I would say you have enough flow.
I don't think they look pale.
If they are pale, I would look at the lack of nutrients in the system.

i am running zeovit. i am running reef crest mode , does this produce enough flow ? i left it at half way . is the mp60 to near to the corals ?

[chercm]

Any one ?

I would also look into your nutrients.

[chercm]

po4 = 0.009ppm

I don't understand what your issue is? You're corals look fine...

[chercm]

I kept losing red and blues

[Jeremy Blaze]

You will only see intense color in the spectrum of light that is provided.

I think a different mix of bulbs would give you a better range of colors.

[Jeremy Blaze]

How long has the tank been set up?

[chercm]

2 years plus

[Jeremy Blaze]

So have you always had problems keeping blues and reds, or is this a new issue?

Was this a sofite tank and you just started keeping sps?

Did you have a die off, or some other event?

[chercm]

Always have the issue as the coral will turn brown or the colour drop

[Jeremy Blaze]

If they turn brown you have a nutirent problem. Judging from the green algae growing on the glass, I would say you have a nutrient problem.

I have never run a zeovit system, but from what I have gathered by others that do they are very labor intensive to keep in balance and keep nutrients under control.

How long have you had sps in the tank? I don't see many that look to be a year or more old, based on growth.

What do you use for calcium and alk? What are the levels?

How often are you doing water changes?

[chercm]

My po4 have been 0.009 and I changed 10% every week with rodi water

Dkh have been 7 as per zeovit recommendation

[JSeymour]

Likely the lack of nutrients if you're running Zeo and have a PO4 of 0.009 ppm(what test/titration/meter are you using?). Spectrum could be it too. Are you utilizing the red leds on your Radions? Maybe add a blue/magenta stunner strip to further enhance the reds and blues.

I'm not extremely familiar with Zeo, but at a certain point, things are supposed to pale out, and then you start dosing various other things like AA, Pohl's, etc to deepen and enhance the colors. What Zeo products(or equivalents) are you dosing at this point?

[chercm]

i used hanna hi736 to measure it . i am running natural mode at 100 %

i do dose b-balance
