Losing color can't figure it out

[Scubapro13]

For the past couple weeks my corals have started to white out pretty bad and I can't seem to get it to stop. I figured tank did not have enough nutrients in it so I have been feeding tank more fish food, reef chili, and reef roofs but I have still not seen improvement. This all started a month ago when I started to use the red sea no3 po4 x realizing after I didn't need to use it. Only coral starting to get any color back is my orange monti cap. My birds nest are almost completely white. Always seems to happen with me with hard corals with both of my tanks. Any help would be nice.

2 primes is A TON of point lighting. what are your settings on them?
I have a single one on my 40 breeder that is for all the frags in there.

Could be too much light.

I have all ready kept them way turned down over the last couple weeks and doesn't seem to be helping. Only reason I got the 2nd one was for more coverage but was very conscience of the power

It will take a while for the corals to recover. Be patient.

The pic i postedwas like a week to 2 weeks old and i have kept everything as stable as possible but I still seem to be losing

just took this picture and much more loss of color

This one was starting to get darker and looking better and now is getting some white on the top

Your lights arent the problem then-that seems very low but I get the thought process there.
How old is your system?
The SPS will want near 0 nitrates (most of them anyway) and the LPS and softies will want 5+.
Its the reason my tank cant support SPS, my goal of nutrients is 5-10 ppm.

is that a leptoseris?

Everytime I go super low nutrients this happens with the no3 po4 x I used it got parameter to zero. The tank is almost a year old but my coral health was much better when my water column was more nutrient rich but it was never over 5 nitrate and .08 phosphates.

Pavona coral that came in a live aquaria coral pack

ah gotcha
and its widespread? lps/sps/softies?
That is odd

 

[ahiggins]

although...Im always wary about nopox and vibrant. (vibrant nuked my tank)

I have no lps but my zoas are doing ok not really liking the low light I have my tank on right now. But all sps are not doing good at all

 

[ahiggins]

what sps do you have?

I bought this pack and it consist of Pavona, Seriatopora, Stylophora, Porites, or Pocillopora

What test kit are you using for phosphate? If they are truly zero using something like Hanna ULR then that could be part of your problem.

Tested at .07 today the last 2 time I have tested have been 0.00. But I have been intentionally feeding more to get it higher
