Coral skeleton dissolving

[Andrew_bram]

I am not sure but I think one of my corals is dissolving. What could cause this other than low ph. Everything else is open and its not stn its the actual whole coral. My alk is 10 and ca is 500

I can't think of anything but a picture would help tremendously.

Id say that if your alk is 10 and calc at 500, your ph is probably around 8.1-8.2 and your wiggin out. It isnt dissolving.

but seriously.. are you runnin a calc reactor?

 

[Andrew_bram]

No ca reactor here I use randy two part and dosing pumps. I swear it is for sure not new growth. It is a purple digitata and where it look to be dissolving is not rtn or stn as its the actual structure that is receding will post pick when lights come on promise I am not losing my mind

Are there any corals close by that might be fighting with it? Not certain that mesenterial filaments are capable of dissolving skeleton...but I don't know what else it could be.

I would say your calc and alk are way to high as well. Bring it down slowly and try to get your alk around 8.3 to 9 and calcium around 420 450.

There are no corals close to it. I thought alk of ten was well within range of target. I can easily lower it slowly but just adjusting pumps. So would everyone for most part agree that is to high

I've had my alk jump to 12 and calcium the same and everything in my tank was fine livestock, sps, and nems :/

I have always ran my all at 12 and my calc at 550 without any issues. Mag has always stayed at 1550.

To tell you the truth I'm not even sure. I have a heavy CA load with some really large clams,sps dominated, and really large LPS. I run a CA reactor and drip kalk

Hmmm...have you checked around the coral for pests? Maybe even frag a piece of a damaged tip and drop it in some CoralRx or something to see if any bugs fly off the coral. If your parameters check out and there are no other corals stinging it...maybe monti eating nudis? ...just throwing out ideas at this point.

 

[ReefCheif]

What kind of fish (if any) do you have in the tank?

 

[Andrew_bram]

I haven't seen anything by way of pest that I know of. As far as fish tonimi tang yellow tang starry blenny cleaner wrasse and clown. I might add no other part is affected on the coral neither is any other monti in the tank
