SPS fading color, bleach, stn from base

[sadaharuflower]

Hello everyone.
As tital.
Some SPS in my 24 cube tank are fading and stn from base.
It seems like malnutrition,but nitrates and phosphates is measurable.
I didnt see any Flatworm
I maintained a basic zeovit system,high efficiency skimmer,carbon reactor

Can you give me any suggestion on this matter?
More coral food? Amino? fish?
Stop skimmer?r
(non-English speaker ,sorry about that terrible English)
kh 7.3
No2 0
No3 20 hanna
Po4 0.05 Hanna
70 gal tank
Par 250-350

Thank you everyone

24 gallon cube?
Too me your parameters and corals look good,
Maybe those corals dont like that spot or something is irritating them
Maybe starving or too much light
Note: On my 50 gallon cube my sps did better with color when i had fish alot and where feeding,
Or some corals just never adapt.

Always i would not stop skimmer,they are the heart and soul of a tank, algae problems
Because most of you SPS look good

Parameters are good. Are you dosing something extra form zeovit? Like zeospur 2
Are corals marine culture?

What temperature is the tank? Any temperature swings?

All the light colored ones look newly glued to the rock with no encrustation, whats the story behind that?

 

[thatmanMIKEson]

Do you have more pictures of the other corals that look ok?

Thank you

I duno , most of his corals have color,
Looks that multibranch looks like some kinda of stag was in that condition t when it first went into his tank . or maybe a parameter was way different.Or maybe just needs time to adapt,
The other one looks like a strawberry shortcake looks like too much light because it does have some colors and good polyp extension

In fact,most of new sps will glued to the rock quickly.
A few months later sps begin fading and stn from base just like last pic.

thank you for reply

I know your numbers look great, but with these pictures it's looking like low nutrition and thin skin, it's not bleached or burnt tips it's overall skin looks thin.

I'm not familiar with zeovit but I have seen allot of tanks on this with pale but healthy acropora like yours, and I know zeovit is a system that must be followed correctly in order to achieve success.

Is this a possibility?

Im not familiar with zeovit either,thats a good point maybe he has to tweaked something, but im scratching my head other corals are thriving he looks like he has some tough thick branched acros in there the humilis and digitfera thriving with good color

They could be un affected or in different lighting or flow there's not to much information to go off no system age when they were acquired were they moved around all kinds of unknowns but they did mention zeovit and that is a low nutrient system, I believe the stated values would even be to high for a true zeovit system. I am not experienced with zeovit.

Could you post your alk, cal & mag?

Alk 7.3-7.6
Ca 400
K 390
Mg 1280
It’s still a young tank. 6 month

Just want to know
nitrates and phosphates is measurable
High nutrient system
Are they same thing?

Sps with thin skin really seems like malnutrition
