I added selcon vitamins to the food the night before the next day the water was super cloudy and 5 out of my 7 fish died. I immediately started to clean my skimmer that had a calcium deposit lodge in the air line and I saw my skimmer not producing bubbles so I cleaned the entire thing. In doing so I broke the skimmer inlet and have to wait for the spare part to use it I’m running carbon now and have been doing water changes. Went to the lfs they said the parameters were perfect to my disbelief, tested it twice same result. Yesterday it looked like eggs were released all over the tank.

It's possible that you had low oxygen from the supper cloudy water. Did you have any inverts in the tank? They usually will show signed first of a drop in oxygen.

Fish died first cleaner shrimp lasted longer then died today I still have a clam that seems alive and sexy shrimp. Did notice the cowries going to the top so I just added an air stone

Another thing could be a big spike in Ph, like when someone pours bleach into the tank. This could kill the fish but corals would survive.

I’m not sure I tested the water last weekend then again the day I lost all the fish and it seems constant the only thing I changed about my regular routine was adding the selcon to the food did the same to the Fowlr and they’re all fine.
