Montipora losing color

[aecarval]

My montipora Superman reverse is losing color and turning white. Can be high light?

High light with no nutrients is usually a montipora killer. Is it new in the tank? I would put it in an area with less light.

Thank you!

I have a similar issue... see picture

the 2 montis are definitely lighter but *both are growing*... doesnt look like bleaching (as far as i know).

Could this be an issue with trace elements?

My parameters have not changed. I do not do water changes as its a 4 month old tank (just test, top up and 2 part solution daily) and have a small/medium bioload.

Chaeto is the only source of nutrient export.

Should i measure and dose trace elements?

RedSea Trace Colors ABCD 4-Pack

Why does BRS recommend this? The Red Sea line of additives is one of our most popular lines. Red Sea has done testing to see what elements corals take up in what ratios. They then developed an entire system to keep your reef tank from being depleted of any single element, while giving your...

Could it be adjusting to the lighting from old tank to new?

You testing phosphate?

Having the same issue with mine. Following.

What are the phosphate levels? If its 0 like your nitrates then you need to raise your nutrient levels

 

[Mikosreef]

You testing phosphate?

Nope. I can.

 

[Garf]

Nope. I can.

Guess my next question

 

[Deephouse_jedi]

Get an ICP test done. I had the same issue, ended up being I didn't have enough iodine. Started dosing Kent Tech I and my montiporas have been super happy and vivid since that.

I bet your PO4 is 0. Make sure you are using a quality test kit.

Maybe its just going thru springtime changes...kind of like what leathers do from time to time

As is alk swings ...

Having run Zeovit you wouldn’t be carbon dosing would you.
when montipora grey out it could be potassium related

 

[Pistondog]

Need some po4.
Most likely too much light.

I see you have many zero readings. I assume you are using API test kits? Some issues that cause this are:

Light too bright
high salinity
low PH
high nitrates
Alk too high or low
calcium low
inadequate water flow
Pests such as nudibranchs

Some your readings are out of range.
recommended:

Temp 77-79
ph 8.1-8.3
salinity 1.025
nitrate < .4
phos < .04
Ammonia < .03
mG 1300
Alk 8-9
CA 440

I lowered the light intensity and it seems to have helped

I am running 2 x nicrew 100w on a 90 gallon

Had the whites at 40% and the blues at 60%

Now the whites are at 20% blues at 60%

I was getting very fast growth with the whites at 40% but the coral was turning lighter as mentioned above.

Now with the white lights at 20% the growth has slowed and nearly stalled but the colors have stabilized. Gotten darker but not like it was when i got the corals.

My guess is that the amount of nutrients/trace elements was not enough to facilitate the speed of growth and the light intensity was probably a bit too high.
