so I've had the 3 corals in the pictures below for over 6 months, probably longer and I just now am having a problem with them.
The candycane has receding flesh on two heads, it is middle of the tank with medium flow.
The birdsnest was thriving and growing so well but about 3 days ago the flesh started peeling off. It is placed high in tank and high flow.
the third one is my blue clove polyps, I have at least 4 aiptasia's that are seemingly killing the coral. Not sure how to proceed with this one.
Ammonia 0, trites 0, trates 0-5, ph 8.3, temp 79, salinity 1.0255, calcium 425, alkalinity 8.0, magnesium 1200, phosphates .56.
I know the phosphates have to come down, but that shouldnt be causing the corals this kind of damage.
Any ideas or suggestions?
