Alk 6.8 (dropped a little when I increased lighting by adding t5) and no, the lighting didn't affect the shrooms since this has been going on 5+ months before adding t5s. No adverse effects to other corals.
Mag -1350/1360
Cal - 440
Nitrate- 13
Phosphate- 0.06
Salinity- steady 1.0255 for over a year
PH 8-8.3
Recent in tank antibiotic treatment helped all the zoas who were having issues but these shrooms have stayed like this.
Got these from two separate hobbyists with clean systems. The smaller one has been in my tank for 8 months, the bigger one for 6 months.
They both developed these dark centers pretty quickly and have been sort of shriveled up like this for a few months.
Par is right around 90-100 in this section and very low flow, but not a dead spot by any means.
Kryptonite is right next to them and has put off babies, as well as a multi colored eclectus, also replicating.
Opposite corner of the tank I have Sunkist bounce splitting and an OG Bounce growing steadily. Yumas do not like my system, have lost 3 king kongs and I added a Godzilla a few months back that seems to be getting bigger but has lost all its Zooxanthelle (it's almost white/translicent).
Aside from some lost zoas, which I presume is mostly from vermetids (and too low light, that's another story) there has been no other coral loss.
25gallon lagoon mixed reef, acros, monti, a Japanese leather, acans and tons of zoas are doing well and growing.
Only abnormal thing from ICP is high vanadium which I can't find the source of (not outrageous but high).
Keeping trace elements in line with captiv8 master dosing solution
Dosing all-for-reef to maintain parameter
Any help is greatly appreciated!
