White slime is consuming my zoo

[Claudio D]

I have some green polips zoo the caribbean in my reef, lately some white slime is consuming them. I tried to blow the white stuff with water preassure and applied some Lugol solution but today it reapeared
When I used the water some grey dust, came from beneath them
Note the polips came attached to the rock when I purchase it.
PH 8,1 to 8,4 fluctuated between night and light on
1,024 o amonia, nitrate and nitrites
4 month old aquarium
Ca 400 6 to 7 Dkh
600gal

Thanks for any help

Frag off what is not affected and pitch the rest... Doe this before it spreads and place frags in high flow asap for at least 4 days....

chip off frags with a hammer and chisel. you may break up your big rock, but at least you'll save some of your zoos.
