What do you mean by that? Actually dump the skimmate back into the water?

I had a bad algae problem and coral STN when my PO4 was at 0. Used seachem flourish to bring the phosphate up.
Although I don't recommend you to do so, since it may cause other problems.
Generally when nutrient are very low, corals can't tolerate high alkalinity.
I suggest dump the food in the tank double as you are feeding now until your fish in qt are ready.
In the meantime bring your alk down slowly, I shoot for 7.5 ish.
As always, don't change many things at the same time.
Hope that helps.

Aside to what everyone has mentioned above.. low PO4, slightly high alk. You might consider increasing the intensity of your lights or lowering your lights' height. I feel like the kessils are a bit underpower. Definitely check on that shrimp.. One reason y I don't have any shrimps in my tank, bad experiences in the past.
If all else fails, you can always do a triton test and get a better idea.. who knows you might have dropped a small piece of metal that's rusting away in your tank.

I've had two episodes of RTN's, last year and last summer.
- first one was my monti cap and birdsnet last year. I pinned point the problem with Alk swing. Newbie mistake, I dont know anything about dosing calcium and alk. I was able to save my monti by dosing kalk, but it was too late for the birdsnest, it kicked the bucket.
- second one was just last summer, pink floyd, pearlberry, walt disney, SD rainbow milli SPS's lost color and got really pale. PE was bad as well. The pink floyd actually turned brown. For this one, the problem was temp. My usual temp before summer was 78-79 deg, but couple days of heatwave, my tank shoot up to 82 deg for a few days,. as soon as I added a fan and stabilized my temp to normal/usual range, corals gradually went back to normal.
With that being said, what is your dosing regime? No power outage in your area to cause temp spike? How about aerosol that could be accidentally sprayed near the tank? Stray voltage? Do you use GFO even if you have undetectable P04?

I'm going to buy a kit today for that .
I doubt the Kessils are under powered for the corals I'm keeping. As I've said before, I bleached a Favia and Birdsnest when the Kessil's were set at 60%. I've sinced dropped the light to 45% and most everything has better PE. It also depends how many Kessils you are running.
I am using a GHL doser to dose ALK, CA and MG. I test twice a week. I ran GFO for a week about two months ago. I took it out immediately after my Birdsnest and Favia started bleaching.

I use Salifert for MG, N, CA. I use Hanna for P04 and ALK. I also double check my ALK with Salifert. I use a VEE GEE refractometer that's calibrated once a week.

The best advice I can give u is stop dosing and let your reef balance out. Right now something is missing or accumulated in your tank and you don't know what it is until u have an icp test. Don't add any more corals buy an ati icp test and send your water out. I like ati since they will test your rodi also and they including self postage to send out your water sample. Just monitor your alk and keep it stable.

I only dose CA and ALK right now. If I stop dosing then I will get an ALK drop. How do you suggest I keep ALK stable without dosing? I just ordered an ICP test.

Stop dosing other stuff not alk. Just make sure alk is stable don't worry about nitrate phosphate cal mag when your test come back then u will know more detail about your water chemistry then u can have a correct plan to fix it.

Every pump has a magnet of some sort so there's always the possibility of the magnets going bad. Just to be certain, I'd check all the pumps and make sure the magnets are intact. Also, check and magnetic probe holders, magnetic veggie clips, anything with a magnet on it.
Also, I may have missed it but what type of flow do you have through the system? And what type of powerheads are you using?

All my probe holders are acrylic. I'm using a Red Dragon 150 as a return and two MP40's. I've turned off one because it was too much flow for my Zoa's and Euphyllia.
Edit: I am using two Inkbird Controllers for my heaters with metal probes but I believe they are reef safe.

If your phosphate is at 0 then your corals are starving. Turn off skimmer GFO anything regarding reducing phosphate. Let your tank run a couple weeks u will see improvement. How is your Coraline algae when u see pink Coraline start growing on the wall thats the indicator that your water chemistry in balance.

I don't have much coraline on the back wall. Maybe I will turn off my skimmer for a few days to see improvement. My nitrate is between 5-7. I don't use any GFO. Another one of my Fungias is starting to recede as well. I'll try anything at this point.

The rocks were real reef rocks.
