Please help tank going down SOUTH FAST!

Chemi-pure elite has carbon, GFO and I feel some other things in the bag.
Get a couple those and throw those somewhere that will get water through it. (rinse the bag well)
or even poly filters.
It's def water perameter based if it's affecting your whole tank.
And yes Acro's can lose all their tissue in hours, hense RTN (Rapid Tissue Necrosis)
if your corals are tossing tissue then that's going to add to the bioload and make things worse so carbon (or the like) and waterchanges will at least slow things down.

Entirely possible this is related to your starfish death. There are some weird critters out in them oceans.

Yes I am using a ro/do system. So I'm planning to do a 50% WC today and another one Tmr or Friday. I'm scared I won't be able to match temp alk/cal/mg exactly if I do a 80% and end up killing everything. So what is the shortest amount of time does it take to properly mix new salt water?

[Aquattro]

You can mix new salt water in 20 minutes or less with a good mixing pump. You don't need to worry about ca/alk/Mg for now, worry about SG and get temp as close as you can.

Did a 50% WC last night. A few zoas still closed. Most corals look ok but my purple acro that I fraged off the rtn base is stripping its base again!!

Do I have to frag off its base again?


Hammer is still showing its mouth

[Aquattro]

The acro will likely continue to recede, so ya, I'd cut it at the half way point. The hammer looks fine for now, I wouldn't worry too much. Are you running carbon?

[Spyd]

Yes, chop it again unfortunately. You will have to keep doing it until it stops RTNing or dies off...

[jason604]

A nice piece to a tiny piece. What a shame. I glues the receeding pieces behind it in hopes it will come back to life. The first initial receeded piece I frag onto a plug looks like its still alive.
