Not sure if this is the right forum,but here it goes.I have approx 700gal looped system.growing clams,torch coral, hammer coral,ducans acans brain.gabbage,chili,ricordea,paly's,button polyps and in my 180 all acro's and monti's.and 10 seahorses in a 125 fuge.My acans 1year old averaged 5 heads now approx 30, same with my ducan.
about 2weeks ago those corals closed completly along with my brain corals and the palys that are on the same rock as my zoanthids.all parameters are fine and every other coral is flourishing. They are also in different tanks.Lights have been changed and I have done many water changes no difference; the only thing that has been added recently is a phosban reacter.I have since given these: to my lfs to see if he can bring them back to health except for 1 acan to see what happens.Also has the owner of my lfs stymied. Any ideas as to what the heck it could be? :bounce2:

you may have added too much gac at one time. resulting in shocking your system.
