Ok fellas looking for a little advice on what could be the cause of this. Here's the situation.
I have 2 LPS and a long tentacle anemone that have been acting weird for the last 3 days.
The Octospawn and hammer have retracted their polyps by about 70 percent. I've seen them retract more than this when I move them but I've never seen them stay retracted this long.
The anemone is deflating every day at about 5:00. It used to do this a few months ago on a daily routine but it has been huge for the last 2 months until now.

Salinity 1.025
PH 8.2
Phos. 0
Nitrate >5
Cal. 480
DKH 9
Mag. 1320
Temp. 76-77
Tank is 4 months old.

Here are the most recent changes that have occurred-
Larger water change than usual last Saturday 15 gallons of approx 60 gal setup. Salinity dropped to 1.024 but has been brought back gradually to 1.025 where it has been for 4 months. Temp dropped 2 degrees during water change and was brought back gradually.
Added flame angel last Sunday.
Added a piece of rock that had a Monti and Digitatis colony and a emerald crab on Saturday.
Removed canister filter 10 days ago.

All SPS still have polyps fully extended.
There is not any algae in the tank other than coraline.

I know Mark is going to come on here asking for a tank shot. I will post it tomorrow when the lights are on. I was just wondering if anybody has any ideas.

I feel like I've probably made a lot of aggressive actions during the first few months. I've lost a few fish. I've never lost a coral unless it was shipped to me unhealthy.

Coule be the flame angel picking at the polyps. Also, sometimes they just like to retract for a bit. Lol

I agree it could be the angel or possibly any of the other changes.  I doubt it is the Emerald Crab.  I would just watch the tank over the next week or so.  Make sure the angel is not picking at them.  My guess is they will probably all recover.  If things start looking worse then they may be a bigger issue taking place.

Sometimes even a good change to your tank (water change) will cause a coral to close up for a few days as it adjust to the new environment.
