HELP Mushroom and zoos dying!

yes i have got carbon and phosguard and zeolite all running as noted before. i havent added anything or changed anything is quite some months. all my zoas and mushrooms are now dead and melted ive been doing 50g water changes daily to clear up the water and try and dilute what ever was killing everything. i am thinking that it was possibly a stow away on a piece of rock like a nudibranch or sea apple whagt went un noticed untill it decided to get stuck in some rock and die and thus killing everything. leathers can tolerate chemical as afterall they release there own form. mushys rely on the nutrients in the water and hence are dependent on a circulation of water throughout themselves where as a leather coral and nems are largers and capable of closing up with differing defences i.e leathers completly close up and are capable of 'shedding'

weird thing is some zoas are completly find and one colonie just decided to go with the crowd and take a ride down the siphon tube and finally get there ticket back on the porcelain express.

 

Sco-tie,

I'm so sorry to hear about your zoas and mushrooms. I certainly hope everything clears up quickly for you and the survivors do well for you.
