Tank falling apart

[keddre]

every invert in my tank is falling apart. My nitrate is 0 and salinity is 1.026.

First was my feather dusters, they popped their heads off, came out there tubes then buried under the sand (still alive). After them was my emerald crabs, I don't have any back story, they just died. Next up was my goniopora that completely fell apart over the course of two nights; the first night they turned into a brown mush, then the next night the mush disappeared, leaving a white skeleton. After that was my Coco worms, they are alive and acting normal, but their tubes are literally falling apart, not popping off. Now it's my sea apple, he's stretching out and one of his tentacles is unaccounted for. I have blindly been doing water changes, but it's making no differences.

Edit: these are my most up to date params as of 11:30 EST:

ammonia: 1.0 (probably from all the doing but WC time)
Nitrite: .50-1.0
Nitrate: slightly under 5.0
PH: ~8.0
Temp: 26°C
Salinity:1.027

test your tank for copper

Ph? Alk?

test your tank for copper

Don't have access to a test kit. I'll see if I can find one around town though. Forgot to add, I have been going hard on activated carbon though

Ph? Alk?

Give me a few for PH. I got caught up in something. But I don't test "reef" params as I only had the one goni and a gorgonian frag

Doing a thorough parameters test now and will append it into my OP

Response from stressed Sea Apple? How large is the tank. Start some charcoal.

Just finished testing and it looks like at 8 months old, it's going through another (not so mini) cycle

He's not responding in a bad way. If he wanted out, he would swell up. He's just stretching out.

55 gallon

I am already running charcoal

Water changes will get parameters back in line.

Good Luck. Some Basic tests to have IMO (salinity,ph, alk,Ca,phosphate,nitrate) for reef and I would add magnesium test latter.

You have a detectable ammonia and a nitrite which means there is decay, that is not from the water changes. The values probably represent the death of the inverts and corals, which will indeed stress out the Sea Apple, which could possibly release toxins as a stress response. I would continue water changes and use some prime, change out charcoal. Did you stir up the sand bed, there looks to be a good deal of detritus. You were probably feeding heavily to maintain the inverts?
