Should I cut this frag to save it?

Total SPS newb here. I'm having a go at SPS in one of my tanks. I have this acro frag that is turning white at the base. It has browned as well but I'm more concerned about the white base. Algae is starting to grow so I assume it dead there. Should I just cut it at the bottom of the live portion and glue it to a plug and hope for the best? I have quite a few other SPS frags and this is the only one showing this concern. I know Phos is high so I'm thinking that my be the reason for the browning and am working on that as well as bringing nitrates up. Parameters are SG 1.025, temp 79, NO3 5ppm (I recently brought that up using sodium Nitrate as it has been pretty much undetectable for over a year) cal 400, mag 1500, Phos 2.2 (down from 4.3 last week) I don't test nitrites of ammonia since the tank has been running over 3 years.

You can but also assure you don’t have low nitrate/phosphate and alk is not elevated as well as calcium low or salinity high

Nitrates have been barely detectable but I have gotten it up to 5 using sodium Nitrate. Phos are high. 22 down the from. 43 last week ,the hair alage loves it. Forgot to list alk and pH. PH varies of course but usually around 8. I try to check it at the same time of day when I do. Alk is 8.3
