Acro Problem Help!!!

[21chip21]

I don't see red bugs or Flat worms. Anyone see this and have a cure?

Do you carbon dose?

I don't think this was caused by any bugs, flatworms or nudibranches. It looks like the corals all experienced stress from some factor related to the water. Since your parameters are fine, I'd attribute the problem of water being stripped of all nutrients (PO4 and NO3 both being zero). If you are running GFO and GAC I'd stop both immediately. Although this won't reverse the progression you may save any other corals which appear healthy. Is the necrosis spreading rapidly or slowly? The only thing you can do if the corals can be taken out, I would dip them every day in Lugol's Iodine,Coral RX or Coral Revive for maximum recommended dose and time until corals recover. I'd think it'll take at least 6 days of dipping to see any positive change.

Let us know how things develop and GL.

Yes I am running two little fish 150 of carbon. should I shut off skimmer and my carbon reactor?

Not running any GFO of anything else, just Carbon and reef octopus 3000. did a big water change. maybe I should dirty up the water some?

My red planet did the same thing, it lost a big chunk of flesh from the bottom. I put superglue on the area And it stopped losing tissue.

It hasn't started growing over it yet, I'm a little shocked this coral is the only problem child I have and it's supposed to be super hardy...weird we shall see.

FYI mine did this with 2-5ppm nitrate and GFO going. All other sps are booming.

Have you handled the corals at all? How old are the corals, they may just be shocked. I wouldn't dump any miracle chemicals in the tank just yet.

your tank does not look low nutrient base on the color of the coral. did you do something to the tank recently? I would definitely cut out the bad area. necrosis usually moves fast.

Every acro in dying from the bottom up. Coral has great polyp extensions and great color. Its a slow death. I don't know what else to do. Anyone???

Iv fraged a bunch of times and it still happens from the bottom frags. Also did coral dips and has no effect.

Verify your parameters by taking your test kits and refractometer to a LFS ASAP. Calcium level of 500 is a little high and if your refractometer is off by just a couple points and you're over 1.026 thats a problem.

Did all the corals start doing this around the same time? If so it could be something environment related. Could something have gotten dumped into the tank? What is your temp? What are you dosing and in what amounts? At this point large WC's are your friend.
