Can I save it?

[TeeSquared1214]

Posted before about this specific coral and learned a lot. Curious if I should still hold on or just call it a lost cause, but my acan echinata has two of three heads I can for sure see some sign of life on. Seems to be about the size of a grain of rice or less. I did notice they started looking substantially better after a water change (20 gallons) on Friday from my 100g display, 130 total volume system. However, they’re back to looking less than good. Still within my first year, and all other corals are doing well.

Parameters as of today (Monday):
PH - 7.8
Temp - 78.4 F
Salinity - 1.027
Alkalinity - 7.6 dKH
Phosphate - 0.00 ppm
Calcium - 460ppm
Magnesium - 1520ppm
Nitrate - 2.0ppm

This is only my 3rd or 4th water change within a almost a year of having this system. I noticed this particular coral perking up after and decided to perform them more regularly and as a result, having trouble getting consistent parameters after just a few days from the change. Using instant ocean reef crystals to the 1.026 gravity.

Should I risk trimming it or just leave it be and maybe start doing smaller daily water changes? Any advice would be appreciated.

I'd remove the bubble algae and otherwise leave it be. Could recover, but not likely in my opinion.

Never say never, but this isn't one i would hold my breath for. But, i have never had good luck with acans.

It will not regrow over skeleton that has algae / green on it, and the bubble algae is going to annoy and sting.

Sorry but this is highly unlikely to save. The time to save it would have been weeks ago

Your alkalinity still is on the low side, and phosphates are bottomed out at zero, that’s no nutrients in the water for coral. I keep mine higher than most. They aren’t as bad as people make it seem. I’m usually .3-.4 phosphate but have run my system as high as 1.04 phosphate. No impact on my lps or sps.

0 phosphate however is definitely a problem

I totally agree with @VintageReefer .
If you can raise your phosphate, I would start there. The coral is starving.
Also, you can remove the bubble algae by brushing with a toothbrush dipped in peroxide.
