Dead sps!

[noah.tank3]

Hello friends! I was wondering if anybody has run into problems in their tank with all sps coral dying suddenly and their chaeto growing red. There isn’t cyano or red algae on the chaeto is is growing red. I have talked to some friends and they said it could be high iron. I have sent in a icp test and ran 6 poly filters. I have also put in carbon and done 3 water changes. My tanks parameters are all perfect. I am at a complete loss.

IMO, might as well wait for ICP results and go from there. Not to be argumentative but parameters are likely off somewhere.

Thank you! I sent it off a week ago I hope it comes in soon!

I would like to know how you made your chaeto turn red.
Something chemical or biological or light is pretty extreme for that to happen I'd guess.
