Coral bleaching

[gaving]

I’ve had this tank for about 10 months it is a 20 gallon cube tank and recently I went into the world of sps. I’ve noticed that both of them are bleaching and I was wondering what I can do to reverse it?

Hard to tell but that looks like tissue necrosis, not bleaching.

I’ve checked all peramaters and they are all stable for the past 6 months I check weekly and recently every other day. Light is a ai prime 16hd

Is there anything I can do to reverse that or is it ok for the coral?

Tissue necrosis is the same as saying it's flesh is peeling off and it's skeleton is exposed. Are the sps in direct flow? It doesn't look like it from the picture. Sps prefer strong, indirect, random flow. What are you using to test your parameters? Can you post your parameters so we can see if something looks off? Any recent changes? Did you do a water change recently?

If it's necrosis, no. The polyps will be gone and that part of the coral is dead. If you figure the problem out and rectify it, you could save the remainder.

If it's bleached, the polyps and skin will still be there, they'll just be white. Bleached corals can color back up.

My last water change was about 1 week ago
Ph 8.4
Ammonia 0
Nitrite 0
Nitrate 0
Salinity is 1.24
It is not in direct flow
I am using a api test kit and Hannah for salinity

Nitrate at zero is not a good thing, get them up...also what is your phosphates at.
it looks like stn or rtn and if that’s the case there is no fix...you could try fragging what’s left

i would also invest in better test kits

what is your alk at, and if they are swinging there’s your answer

Yeah I went to my LFS today and that is what they said could have caused the problem sadly the piece that has this is small and the way the stn or rtn is there is not an area with out it.
