What's wrong with my gsp?

[PPChalk]

I've had this gsp close to 6 months at this point and it hasn't grown at all, about 3 months ago I noticed brown under the polyps and slowly the polyps have begun closing what could be causing this, would an iodine dip help? I've moved the coral a couple times to try to give it more flow, and light but the issue is persisting. The coral is currently in a spot with pretty high flow and a decent amount of light i do not know the par.

Tank is close to a year old and chemistry has remained relatively consistent for last 6 months
Chemistry (I have limited tests)
Alk - 9
Salinity - 1.024
Calc - 1000 (I'm working on lowering it slowly)

Is your Calcium number a typo? Or is it actually 1000? And what kind of test kit are you using?

 

[PharmrJohn]

And do you do water changes? Because a Ca level that high can affect organisms.

The calcium is that high and has been up to 1400, I'm using a nyos test kit, I don't typically do water changes but have been doing a weekly 5 gallon with instant ocean to reduce it the system is 140 gallons. I'm not sure how it reached that number to begin with but I has likely been that high since I introduced coral so I'm taking things extremely slowly. Everything is highly colored up and most corals are growing well. I recently experienced a 72 hour power outage where one of my goniapora bleached but most things are back to their old selves. The gsp is looking significantly worse though.

In the second picture it looks like its overgrown by coralline algae (which draws calcium from the water to grow). In the first picture there is aiptasia on the side of it. Not sure about the brown stuff but that doesn't look good either. Not sure about dips.

The calcium is that high

Definitely living up to your board name

Possibly the aiptasia that is growing out of it

May have something to do with your GSP dying

The gsp has been Browning for 3 months, the aptasia is a new arrival. Are you saying the brown flesh of the gsp is a result of the aptasia stinging it?

I think the pink coralline looking thing in the first picture is dead flesh of the gsp

No

I am not saying that
