Hairy shroom

[sharkbait1122*]

So I have this guy at the bottom of the tank sitting around 60-90 par. Was doing well for a while but now is looking like it’s bleaching?
tank par;
Alk 165ppm or 9.2dkh
Calc. 430
Mag 1440
Phos .25 (high I know) working to get it lower
Nitrates around 10

many thoughts on what to do?
I did recently have to blast off some sand from it from a shrimp and I just finished battling some cyano. Not sure if that’s contributing or not.
Also have two lps doing poor, a Duncan and hammer:/

Well those parameters all look fine to me, especially for a rhodactis mushroom. They typically can handle higher nutrients. My tank actually hovers around 10-15ppm nitrates and 0.15-0.20ppm phosphates and everything is thriving so I don't think high nutrients is the issue. Being buried in the sand, especially if it was several days or more can definitely cause issues but I'm guessing it wasn't that long. I didn't see your salinity listed, have you checked that recently? Also what kind of flow is it getting?

@muzikalmatt salinity is right at 1.026 and it gets indirect low-low medium flow.
It sits directly under my light but like I said the par is no more than 90 due to shading. I’m presently a bit stumped.
