My experience with NP=0 coral is no problem, my standard is P < 0.03 ppm

Coral nutrition supplement, usually Zeo CV, AA, Xtra,...

Low malnutrition, stable water quality, very good

Low malnutrition water quality, keeping water parameters inline, including potassium

Because it is a system conversion, I don't know how to distinguish
Through the appearance of coral, tissue becomes lighter, polyps grow, good PE

This is usually the period during which the ZeoVit reactor flow is switched to continuous flow for about 2 weeks after the first ZeoVit exchange."

Notice the thin and receding tissue at the base of the acropora. In my experience, this is caused from low nutrients. I know zeovit is a ulns and supposed to be heavy in, heavy out. Should I be dosing more than just 2 drops of SP at this time? I have hanna Phosphorus packets coming in the mail today so I will repost my system parameters once testing is complete. If I need to dose more for coral nutrition, what should I use? I have available in my cabinet:
Sponge Power
Coral Vitalizer
Zeofood
Xtra Special
Coral Booster
Flatworm Stop

From the case of red algae, I don't think corals are hungry, they are more like new growth. I don't mean bad, maybe I am wrong.

The growth edge is recession. It is loosing tissue, maybe it's not as visible in the picture as it is in person. There is no algae in the system other than coralline

No3 tested at 0 while PO4 tested at .098. Could it possibly be too much flow through the zeostones? I can lower the flow rate with the feed pumps adjustable pump cover

If the corals are healthy and maintain the correct ZeoVit flow level, use the basic method of adjustment to add and reduce the phosphorus product addition, which will be more appropriate.

Sorry for my negligence, #11, #14, is still 3 open 3 off state, give the system some time

Does the coral appear to occur before the system is converted?

I would first recommend to cross check your KH and Ca test result with a different kit. Additional doing two 15% water changes within a week might be helpful also. I do not think it is a result of “to low” nutrients like NO3 or PO4 or a leak of coral food.

Sorry, my interpretation is not good, which means that from the color of coral algae, the bottom of the coral is usually kh, as G. said - Kh Ca, then the salinity Kh Ca Mg K+ is also tested at the appropriate level. And changing the water to refresh the element balance

Those levels are close to perfect Brandan, this should not be the reason.

How much carbon do you have running and do you use it in a reactor ?

Please also measure the reactor flow by collecting the water from the zeovit reactor outlet for 30 seconds with a small container. Multiply the volume by 120 and you will get the output per hour. Should not be higher than 50 US gallons per hour.

Not running any carbon right now as all I have is ROX 0.8. Need to order Zeo carbon. Flow through reactor is 48gph. With that said, recession seems to have stopped and color completely changed

I am very happy to hear this good news, the corals are healthy and very good.
