Bleached Bali Shortcake

[ccole]

I’ve had this frag of Bali shortcake for about 2 months now. In the first couple of weeks, I put it under about 450 par and it bleached pretty badly. I moved it to the sand bed under about 150 par and it is recovering very slowly. Should I move it to more par or leave it where it is until it colors up more?

The lighting is 3 uno pro 2.1s with 4 T-5s blue plus.

I’m not having any other bleaching problems with SPS.

Water parameters:
Calcium: 420
Alkalinity: 8.3
Phosphate: between .05-.09 (dose every day)
Nitrate: 35
Magnesium: 1380

Edited because I accidentally pressed post.

Does anyone have any recommendations on PAR for this coral? This is in my daughter's tank and it just doesn't seem to be improving much. I know it takes time to recover but wanted to give it the best conditions possible.

If it's not getting worse just leave it lower............make sure flow is good. You should see it get darker in 2-3 weeks. Monitor closely............pictures from above to compare can help in evaluation.

If it's still very pale or gets worst move it to a shaded area. As the zoo repopulates it may turn brown then I would consider moving up.

I've had severely bleached corals recover.............it takes months not weeks before they will be thriving and growing.
