You don't have to diagnose the problem exactly, because the treatment is
the same. Clearly your water is screwed up. Replace it.

Of course you can't just dump in fresh water.
But you can do a huge water change. In a 180g tank with totally messed up
water, you replaced 25g and hoped that would fix it?
Try replacing 75-100% of the water.
It would be best to do it all at once, but it's almost as good to do it in
stages, if you can't make that much new water at once.
E.g., Replace 50g every six hours, four times in a row.
You wouldn't ordinarily want to make such a drastic change, but that's because
ordinarily your existing water is "ok", and the animals (fish/coral) have
adapted to the current conditions.
Not so with your situation. Your animals are dying in their current water.
The solution? Change the water.

You need a massive water change. Immediately.
Good luck,

To me, truth is not some vague, foggy notion. Truth is real. And, at the same
time, unreal. Fiction and fact and everything in between, plus some things I
can't remember, all rolled into one big "thing." This is truth, to me.
