Yumas bleaching

[thesoulpatch]

Hey everyone I have a rock that has about 5 yumas that when opened are aroun 1-2 inches, and about 12 little ones that are the size of a pencil eraser....

Recently they have started to bleach and turn white, the tips still have some color but are turning white as well. They haven't been moved from in the tank since I bought them several months ago and I have fragged and sold many of them. The lighting hasn't changed, I've done my biweekly changes and the params are 0/0/5. I can't seem to find out what the problem is and why they are turning white.

I have talked to several people about this, including my lfs, and most people have said turn the lights down. I have and now I'm wondering if there is anything else that can be done to help them heal.

Others have said use a coral dip such as Coral RX, but I feel that would stress them out even more and possibly kill them....any ideas other than just put them in a low flow, low light area and wait and see?

What are your numbers please include po4 and No3. I’m assuming 0 is ammonia 0 is nitrite and 5 is n03

Have you done anything different to the tank before they started bleaching.

so the advice you've been getting is to adjust the light that all the corals in your tank might be thriving under in order to save a single coral that many already consider "finicky"? I would take that advice with a grain of salt.
get your basic 3 parameters measured, your salinity with a properly calibrated refractometer and check your nutrients (NO3 and PO4) before you go messing with what is not wrong.

The only thing in this tank are the mushrooms, 2 zoas, and a frog spawn. Sorry I forgot to specify that it was a grow out tank.

The ammonia is 0 nitrite is 0 and nitrate is 5

the phosphate is around .04

the salinity is 1.025 as I just did a water change yesterday.

And no nothing has been done to the that tank for several weeks, almost a month. I noticed this last week and they have slowly become more white as time has progressed. I been keeping an eye on everything and nothing has really changed at all. Other than the coral turning white. The other corals in there are happy and open.

What’s the temp? Are they closed or opened? A pic may help.

 

[thesoulpatch]

They are open, the temp is currently 78.

I'm working atm and I forgot to take one last night, but I'll post one in the next couple hours of them once I'm home.

[sfin52]

Anything close that may be irritating them.

 

[thesoulpatch]

Nope. The closest coral is 3 inches away and a zoas

 

[sfin52]

Some of them look like they still have good color.

 

[thesoulpatch]

The color is only in the tips of the corals.
