help with white areas on birds nest

[LovesDogs_CatsRokay]

What would cause this birds nest to lose tissue in the middle of its branches like this?

Params as of Saturday were:
Ca 415
Mg 1280
Alk 8.6
P04 0.08

I dosed Vibrant on Tuesday to try to help with all that algae going on. That shouldn't have caused this, right?

Warmer temperatures and pollutants I would say are the culprits. It looks like white plague disease which is similar to white band disease in Acropora species. I would ensure that your thermometer is working right and at a optimal temperature. Check if you have stray voltage. Also, you may want to break off pieces of the colony by cutting them without getting any dead tissue as part of your cuttings. Just cut into the healthy tissue and you may have a chance of the coral growing. Otherwise, the bleaching will overtake the whole colony I’m afraid.

Thanks, I’ll have my husband check for voltage tonight, but Apex probe and also a magnetic thermometer say the temp stays between 77-78 degrees all the time.

How long have you had the Birdsnest? Did you acclimate it slowly? What kind of lighting and water flow?

It was in my QT tank for a few months doing wonderfully. It's been in the DT for a couple weeks. The params on the two tanks are close enough that I just did a quick swap. The lighting is provided by the new Red Sea Reef LEDs. Flow is pretty good I think. Its a 4ft tank with an mp40 on the end opposite the birds nest, and an ice cap gyre 1K behind and above the birds nest.

I rechecked P04 last night, and it has jumped up to 1.3, presumably from the vibrant dose and algae die off. Would that have caused that? Nitrates are reading at 10.

Oh, and I dipped it last night to check for pests, nothing came off.

I feel like for something like that to happen to birdsnest, then something is really off in your tank. IME with BN, it’s usually the last to die. Unfortunately with tissue necrosis, sometimes it’s difficult to say what caused it. You’re positive your NO3 10 ppm? I’ve had BN tissue peel away at high NO3 and PO4, which may be your case seeing how much algae you have? Just a thought.

Nope I’m not positive N03 is 10, but that’s what my Salifert test kit said. I have a different birds nest on the other side of the tank that’s doing ok. As well as a few acros that are doing okay. Good PE and a bit of new growth on the Acros.

Hope you get it figured out. I wouldn’t worry if all else is fine though. BN is easy to replace if need be.

I hope you fine out why it happen.

because I am the same with you sps.

ORA stylropora, BN can be survival in my tank.

My BN did a very similar thing right at the being of a mini crash. It started with the BN turning a pale neon green then died from the inside out. Something is wrong or not stable. Mine was an ATO failure.

Its funny - I literally can keep multiple orals - but I cannot keep a birds nest in my tank. I have tried and tried. The same thing happens as to the OP - I've ascribed it to some toxin in the water - perhaps produced by another coral - but it just doesnt work for me.

On a positive note, those guys are pretty hardy! It will come back!
