Default Sps coral bleaching slowly from base

As above I find 2 sps coral- a.cerealis and a.microclados doing well full polyp extensions and showing growth tips
But it's slowly TN from base up.

What could be likely culprit? I blew for aefw-negative. All other corals are doing fine. Using hybrid T5 and led lighting; plenty of light and lots lots of flow in tank.

Corals are highly sensitive they die off all the time. 10% of the worlds coral is already dead. by 2030 90% of it will be in danger by 2050 All of it will be gone.

the situation on your coral will likely continue until the whole coral dies. All you can do is gamble on buying healthy specimens and have them grow and live

Trouble shooting in most case is futile; not a lot of work has been done on coral health as it yields no money to practise and figure out cures for dying coral

Might be the source of the corals be different so for example the two are coming from Australia ?

Hi Alex. One of them is wild Aussie. The other I'm not sure. Any solutions that can help?

I have a tricolor acro that grows spectacularly, with good color and very widespread polyps, but since about a month ago it has been whitening at the base. I'm already considering cutting it, giving it a rx bath. I think if I leave her as she is she will finally die.

You have to remember that top dwelling corals that crouch just beneath the water have short lives spans. They generally grow up in a few years then breed and in a matter of a decade bleach from base outwards.

Really difficult to say, are those corals placed in a area with lower water flow ?

In my case, no. they are all at the same level. For now I'm going to cut a piece so as not to lose it.

That's a fine looking tricolour, Zebra. You checked for Aefws?

Theres also loads of flow in my tank due to several mp40s. Really stumped as the TN is slowly getting worse from base up.

My first suspicions were there, but I add 3 ml of FWS 3 times a week and the truth is that I apparently do not see anything. I believe that for a low level of trace elements (According to triton lab) and lack of food can be the cause.

I add 3 drops of coral vitalizer 3 times a week but it is not enough, I wanted to complement it with Coral booster but I have been waiting for the product for more than three months now. No3 = 0 PO4 = 0.02

This week I cut the acro tricolor and the truth is that they look very good, without bleaching in the cuts. I hope it is saved because it is one of my favorite acros.

Yes, unfortunately the TN advances slow but unstoppable, hence the idea of cutting above the whitening so as not to lose the whole piece.

I would also check for flatworm especially AEFW. these pests start their way from the base and lay eggs there as well.
a dip for one of the corals can reveal if you are dealing with FW.
dosing flatworm stop is always good in my opinion and worth the peace of mind.
