HELP ME! No one seems to know what is killing my fish!

[Salty_Hobby]

I have a skimmer fit for the size of tank and a filter on it, it was ok before with some die offs if I didn't do frequent enough water changes but I've been good about them lately.

The ammonia kit should be ok, I've done tests in the recent past that were zero for ammonia. I don't have any film on the water surface, just the glass and stuff inside the tank under the water. I don't have any snails, other than 2 tiny ones that came with the live rock way back in Feb.

I will keep up with the water changes every few days, the ammonia levels have come down but not by much I'm only panicked because I feel terrible I am killing my fish!

Thanks everyone, I will update in the morning with how the increase salinity, temp and Stability additive for ammonia works out.
