Cannot keep birdsnest coral alive longer than a month or so

[javisaman]

The last few birdnest corals I've had from frags eventually RTN. They usually live for about 1-2 months, then over the course of a week will lose their tissue, then lose their polyps. My other Acro's are doing fine, as well as montis, LPS, and zoas.

Lighting: 3 x XR15 Pro (peak 35%) + 2 x ATI Coral Blue plus + 2 x ATI Actinic (9 ramp up led, 5 hours T5 peak)
Flow : 2 x Sicce 3.5 returns, Vortech MP40 QD, 2 x gyre 330
Params: 8.7 dkh (Hanna), 8.6 Nitrate (Hanna), 0.03 Phosphate (Hanna), 420 Ca (Salifert), 1300 Mg (Salifert), Ammonia 0.0-0.15 (Salifert)

The coral is about 14" from the surface, while the lights are exactly 13" above the surface. This is/was an ORA birds of paradise. The picture was taken with a 15000K orphek orange filter.

Not sure why there is a video upload feature for posts when the videos don't play

Birdsnest are either easy or hard I find.
I have tried a couple in the past and experienced the same thing.
This year a club member threw me a couple and they survived. The only thing different is I have a controller and stability has gone up.

For me this is a pretty forgiving coral..
Not sure whats the problem here when even acros are doing fine though

For me, it seems like it is too much of one of the following: light, flow, instability, lack of nutrients.

I should add I have no fish. I feed rotifers, acropower, and reef roids on occasion.

SPS and no fish is usually a problem…
Add fish, feed them and dont dose anything else.
I made the mistake myself..
Then I started to listen to experienced sps keepers…

All you need is:
Add Fish
Feed Fish good (import)
A good export tool

You really dont need anything else

Your xr15s may be too far from the water. BRS did a video and recommended them be 9inches off the water
