Slow tissue recession

[tbaquatics]

What are some things to check on LPS (scolys, acans) that slowly recede and show skeleton. Very slow. They are currently on the bottom of my 120 (4 ft version). Lighting is 2 x 175w MH/VHO just above the top of the tank.

Calc and Alk are ok.

IME they are pretty sensitive to lighting changes. If it came from lesser light maybe you can partially shade if for a while. Look for it extending its tentacles at night and feed it.

They have been in the tank for months, these are in my personal tank. Not sure why this got moved to coral farming, I don't do that anymore...

Do you have any fish that pick at corals, like dwarf angels?

Check your RO/DI TDS & DI cartridge depletion.

Do you feed them?

australian ? read a article on RC where guys were having issues after awhile with australian corals and did a red bug dip or revive dip and cured the problem, add anything new to the tank lately ?
