Tank is crashing :(

A few questions:
Did you measure the PH before and after the addition of the calcium reactor?
Do you have a sandbed?
What light fixtures were you using and which ones are you now using?
What do you have for water circulation?
How much GFO have you been using and how often are you replenishing it?
How long has the tank in it's present state been running for?
Can you post a link to the Walmart nori?

Please post a picture as mentioned above.
I'm not a fan of GFO because it will remove trace elements, so I would recommend a larger (25%) water change sooner than later.

My ph before the reactor is 8.3 and with the reactor it did with it it's about 8.2 and would drop to 8-8.1at night.
I also have a ph probe right in the reactor as well measuring a oh of 6.7
Yes I do have a coarse sandbed.
At first I switched from 2 tek t5 fixtures 8 bulb each to 2 vertex illumina fixtures. My latest set are 5 mars aqua fixtures along with 4 36" t5 bulbs.
For water circulation I have 2 maxpect gyres that will blow the sand around if not turned down.
I run 1000 of gfo and that lasts me about 2-3 months. I have 7 tangs who poop a lot lol
This tank itself has been running for about a year but the live stock has been with me for about 5 years while upgrading tanks .
I tried looking earlier on the Walmart page for a pic of the nori but I couldn't find that exact one sorry.

It's been a while since I posted a pic. Can anyone give me some instructions ?

I hope that helps

Have you double checked salinity with another refractometer? I've almost wiped out a tank slowly with a broken refractometer, Just a guess. looks like something is irritating everything as even the trumpet coral looks to be receding.

Sure hope you figure it out tanks beautiful.

Your tank setup looks fine, but your tank has been through a lot of changes in the last 6 months including light changes, changing from dosing to a calcium reactor, alk fluctuations and the use of carbon dosing plus you have a mixture of lps and sps. You didn't mention if you were using activated carbon, so that may be a good idea to compensate for the allelopathy (chemical warfare) between your corals.
Bottom line I think your tank needs some stability, but start with a regular water change schedule.
Turn down the lights and increase water circulation. Water circulation is as important, if not more important than lighting.
imo

I just recalibrated the refractometer and the tank is sitting at 1.024

Iceman you said you neglected the RO filters my guess is chorine got into the tank.
