SPS - Birdsnests/Acros - Q's

[Grandlotus]

Hello,
So my water params are:
Ca -400 (working on getting up to 440)
Alk - 9
Mag - 1400

I have a birdsnest that is looking worse and worse over the course of a month.
I also have 1 acro that is not looking well, but ten others that are thriving.

Any ideas on what could be the issue?

Setup details? Also details about localized conditions for these pieces, like lighting and water motion? Pics?

There has to be a sticky format that people should go by when requesting help that lists.

1. Parameters
2.lighting
3. Flow
4.pics
5. Dosing/feeding
6. Tank maintance

1. Already listed
2. 2x Radion Gen 2 at 55%
3. 3x mp10s
4. lights still off (will post laster)
5. Dosing 2 part daily/coral feeding 2x a week and pellets daily
6. Standard media changes every 3 mths, clean glass, pumps, ect every 6.

What's your phosphate levels at??

While Alk, Ca, and Mag are all important, I think P04 levels are just as important.

This gives a bit more info, but we still don't even know tank size, water change schedule, etc. Believe me in that I am not trying to be a jerk, I promise. You just honestly cannot provide too much information in instances like this, as almost any little thing can count or be critical when overlooked. Things are too vague from which to draw informed conclusions. As much as I'd like to be the reef info equivalent of MacGuyver, I know I can't do it. Nobody will be able to come up with every little detail, as those are often fleshed out as things progress, but we do need somewhat of a baseline.

Whoops, I did forget my tank size... 65 gallons with a 15 gallon sump. refug in the sump with chato. I have a media reactor with GFO and a second reactor with Carbon.

I will pull a PO4 reading before work today and post a few pictures.

All of my other corals are looking great (acros/millies/stags/ect)

Pulled a salifert PO4 Test and got a solid 0.00ppm

Don't know how to edit so here are the pictures:

ponape birdsnest that normally has blueish polyps and the whole coral is slowly bleeching:



Acro that is similar to Pearlberry (seems to be RTN'ing):

Is that cyno on the sand?

 

[Grandlotus]

That is not cyno, have a small dyno bloom.

 

[Amphiprion]

Have you been feeding less, less often? Any changes in additives, salt mixes? Have you ramped up nutrient control (GFO, carbon dosing, etc.) since the dinoflagellates?

 

[Grandlotus]

Its my dad's tank and he apparently is color blind and could not read his test kits.
The calcium has been brought up slowly from 290 over 2 weeks to its current 400.

Same feeding, same Bionic 2 part, same salts, I changed the media out about 1-2 mths ago and added a fished for a total of 4 fish in my 75 gallon system prior to the dinoflagellates bloom. I personally can't figure out the dino bloom, but am more worried about the corals at this point (I know its all related).

Cut down on white light for these. I've burned them also. Can't handle same light as other corals.

 

[Voodoo Corals]

Cut back on feedings also. Do you have a big enough CUC? Are your nitrates okay?

Going in circles because not all info was given. Makes members not want to chime in.....

I will look into this today, but that radion ecolive is such a PITA...

I have cut back on feeding. Some people recommend every other day for feeding fish...this seems wrong and I just do one feeding until they stop eating (3-4 pellets at a time).

I thought this was a more simple question and answer, I am by far an expert, even after reefing for over 5 years.
I am still learning and have much to learn.
Thanks for all the help so far.
