Help!! Is my tank crashing?

[IslandLifeReef]

I was doing some maintenance in my tank by blowing off the rock and when I got around my Hobgoblin Leptoseris, the water blew on it and it turned purple. It has never done this before. I don't know what to think. Can any of you please help.

Parameters;
Temp - 77.5
Sg - 1.025 refractometer
Alk - 8.4 dKh
Calcium - 440
Nitrate - 2.5 ppm Red Sea Pro test kit
Phosphate - 0.0276 Hanna ULR phosphorus
Nitrite 0 ppm

Here is a picture of what it did.

The area at the top is now light purple.

Again, thank you for any help.

I should also add that one group of Zoa's isn't opening and my Acan is deflated. Does anyone have any ideas? I'm worried that something bad could be going wrong in the tank. Also, tank is a little over a year old.

Its hard to really make out anything in the picture... could be that the flesh got blown off? I cant really see anything in the washed out blue light spot, but it looks like that lepto is missing some flesh...

Besides the 3 corals you is there anything else looking abnormal? Kinda need more info to say imo your going through a crash. Do you have mushrooms in your tank? When i went through a crash all my mushrooms detatched from the rocks and floated around.

Yes, I have mushrooms. Other than what I mentioned, nothing else seems out of place. All of the fish are happy. Frogspawn is plump. Duncans are well extended. Other SPS have good polyp extension. The Acan looks normal now.

I didn't see any flesh blow off. It just turned purple. The only way any flesh blew off and I didn't see it is if it immediately disintegrated.

I think you are ok. When suddenly you blast them with strong water flow they might not happy and retract. Give them sometimes they will open up again

Here is another picture with all of the lights on. It does seem to be getting a little better. It's just really weird how quickly the color changed.
