Weird White debris floating around a sticking to everything?

[JOE CERILLO]

Hey guys, So i have a 40B

Parameters are

ALK: 12.5
CALCIUM: 430
MAG: 1230
NITRATE: 11.3
PH: 8
PHOSPHATE: 0.33

I did just change from Cora life to red sea coral pro salt. And the only new addition to the tank is chaeto. I did have a coral that died but i took it out of the tank once it went completely white. But i feel like since i don't have a TON of corals its making my alk too high. So i bought a box of fritz salt (blue box) for the next water change. I'm sad there's so much change going on with the salts, idk how the tank will respond but anyway.

Since i added the cheato i have been getting this white debris floating around and sticking to everything. It does seem to be worse IN the refugium. I also added a Diamond Goby, who is definitely churning up the sand lol

However i have seen my nitrates and phosphates go down since adding the chaeto.

Maybe you guys can ID it so i know what and how to fix it?

I'm going to throw this out there: Any chance it's your calcium precipitating out of the water due to the very high alk?

That was my guess, but I’ve never seen or had the issue before to co firm

I’m really starting to think it’s the chaeto dying off and breaking apart into the water. This is the second time I’ve had macro die in the first week if so…

there was a lot of “stuff” covering the whole ball. Like a dusty coating, similar to what’s in the tank. I shook it off and took a picture of it.

did another test today, everything is looking better.
Nitrates way down.
Phosphate is up a little bit?
Calcium down 5ppm

I’ll attach a pic of todays parameters.

Maybe do a waterchange to help get those numbers down?

I have that too.. but they are moving! the ones on the glass I mean
