Something is wrong...

looks like brownjelly to me , if thats the case you could lose some of your lps , the torches,hammers and frogs are the first to go , then brains lobos etc.

it spreads easily and could have came in on any coral that ypou bought recently.

as for the sps dying and softies closed i would think reaction to the dye off and loose jelly floating , as matt mewntioned i would run carbon very aggressively , also i would syphoin and remove any dying flesh on the lps .

lots of flow right now for a bit will help as will a fresh batch of water.

brown jelly is usually caused by a bacterial infection depending on the coral and type ive had great success with furan 2

if rtn starts to kick in for your sps then its safe to say some solid actions need to be taken or you could lose it all fast
