Yumas are melting and shrinking —— help ——

[Fishingandreefing]

Yumas were all doing well then about a week ago started going down hill but other corals are doing fine.

My alk was low at around 5 when the yumas were doing good. Then I slowly raise it up to 7 in 2-3 weeks.

Tank is 9 months old, 70g running radions Coral Lab soft/lps at 20%, par reading at around 50-70. Nitrate low at around 1, phosphate 0, around 7, calcium 450, mag 1350, salinity 1.025.

I am currently dosing 15ml neonitro daily try to raise to at least 5ppm. Also feeding more to raise phosphate from 0.

I am suspecting the carbon Rox .08 being too strong but I only use about 28%.

lastly, I have heard that yumas are finicky like that but just want to pin point what I need to do to prevent further losses.

Any help is greatly appreciated

Any pictures? Could probably help us narrow done and provide options.

Also, I target feed them with Red Sea energy daily

Obviously you can tell which ones are melting sways

Are your parameters off? Or high par? Pictures?
