Issue with my green sps

[Squadir]

Hey again guys, I'm having an issue with most of my green sps, other colors are fine (orange, pink, purple, blue). Green monti cap, green slimer, bird of paradise birdsnest, green stylo and chillipepper monti are the troubled pieces. My jingle bells monti is fine. The green was coloring up nicely after a few weeks of introducing the frags then started to get washed out on all species and the color just isn't coming back........ Any ideas Why this may happen?

lighting - LED (75% blues 40% whites)
nitrates and phosphates - undetectable
salinity - 1.025
temp - 78-80
calc - 460
alk - 11 dkh
mag - 1380
vodka dosing
started dosing acropower to see if that would help.
feed with coral frenzy twice a week

Only recent changes have been the addition of an ATO 2 weeks ago and a dosing pump 1 week ago.

I know green colored corals, generally need less light than blue or purple etc, so maybe move the corals down, or back off your LED's a smidge, OR throw some window screen over the top of the tank to help diffuse some light. Also, I would try and bring your alk down slowly to somewhere between 7-8......11dkh is a little on the higher end of the chart. Speaking from my experience, my corals didnt do very well when I was running 10.5dkh. I also believe you want to keep alk around 7 or 8 when you have really low PO4 = burnt tips. Hope this at least gives you a few ideas.

I'm wondering if maybe my lighting period is too much, I run actinics for 14 hours and white for 12.........

 

[MontiFanatic402]

Could you maybe post a pic of the corals your talking about? Have you changed lights, or done anything different to your lighting schedule? 12hrs total is about the cut-off, from what I've seen, but some people run more, some less.....every tank is different

no3 and po4?
alk is high. but maybe your nutrients are too

im gonna go out on a limb here and say your nitrates need to be above 0.

I have found my green colored across to suffer in the past due to too much light.

i'm gonna cut back on dosing my 2 part by half till the levels drop a bit then maintain at8-9. Yeah they are undetectable/0... might try to raise them a little and see if that helps. feeding more often should help raise nutrient levels right?

i'll cut down a few hours gradually and see if that helps any.

yeah get nitrates above 2 and turn gfo off

should i cut back or stop carbon dosing also? (vodka)

id cut back and see if nitrates get detectable

Look into the Iron theory, green is easy.

thank you, quite a bit of info in there. i'll do some more research on the iron dosing method.
