I think you're not feeding enough. Your rocks are too clean.
I would up your feeding and use just frozen food, until you start registering nitrate of 1.
You can then cut back a tiny bit if you still want zero, but then you know you are feeding ok.
Corals commonly stn from the base when there is not enough nutrition as these parts are relatively shaded and don't get as much light for energy...... This is more common with Biopellets. They are very efficient!.

Thanks for the help...
But ur also talking about the last picures...
And am feeding I have arounf 14 fish in my tank...
But I run biopallets and phophate reactor and refugium...
To keep my water clean...
I can add zeo extra. Waht do u think???
Plus since I started this tank everyone and everything said to keep my water clean as possibke now am gerting reviews that they are hungry...
So am a bit lost am always afraid to lose the color of the sps and lps...

It's a fine balance and everybody's tank is different.
You have biopellets- very efficient at removing nutrients. Can easily over perform.
You also have a refugium- will strip the rest.
You also run Phos remover.
I'd guess you have a big skimmer too?.
This will likely keep your water very clean. Clearly it does as your nitrate and phos are zero….. but these test kits can't tell you if you have hardly a trace of nutrient or it's close to eg 1 nitrate. Both levels will read zero. There are organics test kits, which can tell you how much DOC you have, but they are difficult kits.
You have to use surrogate markers. e.g. algae on rocks, coral colours, tissue mass etc. to determine how you are running.
Your system either has loads of urchins etc to keep the rocks that clean, or your nutrients are too low to support significant algae growth. My guess is the latter, because you are running pellets…. How much do you run on what volume of system?. What skimmer?.
There is no harm in increasing feeding for a while. You can always cut it down again, but if your corals start colouring up within a few weeks, you will have your answer.
I found that if you start dosing too many Amino's etc, you can quickly feed cyano and it then takes ages to get rid. You have to make changes very slowly or you will quickly get lost about where your system is at.
The other thing you should check is for SPS pests as they eat away the base of SPS too.
What you must not do is make too many changes at once. Feeding more and watching your nitrate/ phos levels carefully shouldn't be too much of a problem and is reversible….. You drop back to your normal level of feeding and within a few weeks, you should be back to where you are now...

My skimmer is reefoctupus for 350 gallons my tank is 180g...
I use vertex illumina 260....
Mp 60 but going to take out and replace it with 3 or 4 tunze. ..
I dose manual untill I decide wither go with caclium reactor or dosing pump...
I do water every 20 days 20%...
I have plenty of snails and crabs ( if a fish dies it needs one day to see the skeleton)
Btw some times I see a small crab on my sps....

Just saw these pics. They look a lot better.
What did you change between the two pics?.
