Zoas melting

[Nano]

well it looks like the shock from what ever happened in my tank is melting 90% of my zoas, 2 ricordea are detaching themselves from the frag plugs and I am down to one snail. So far my zoa casualties are,
blue eye blondes
purple hornets
radioactive dragon eyes
orange oxides
xmas
supermans
teal rings
green tea paly
orange explosions
some pink ones
dennys mix frag
watermelons
possibly my hammer and frogspawn as well.

what a bummer. thats a good $400+ worth of corals
