What did you raise your magnesium up to? What is it at now?

I actually went for 1600 ( I followed the 100/day as the thread described) and left it like that for about a week. The fish didn't have any ill affects. However I lost a coral and my snails seemed to be affected. The Bryopsis turned pale to white and I pulled out as much as I can during the treatment. The Hair algae didn't seem to be affected but I pulled those as much of that out too.

I"ll have to check what it is now but I assume that it would be much lower. The fish also wern't exhibiting deteriorating charachteristics. It was like they were totally fine one day and a few hours into the next day they were dead

I am also skeptical that it was oxygen that caused it, which is why I asked about the magnesium. I'm wondering if you caused a big change in magnesium when you did the 30% waterchange which then may have been the culprit...?

You did say that you just changed salt. Is this the first waterchange you've used it on? Maybe it's a dud pail...

Yep I switched from Instant Ocean to Red Sea Salt. This is my second time using the salt. I did a 30% water change with the new salt before the Magnesium treatment. I didn't realize that the salt can be bad. I did exactly what I did the other times I've replaced the water. before the Magnesium treatment I was doing 30% water changes every two weeks.
If its not the oxygen levles, then I'm completely stumped, aside from the salt and the skimmer not powering up right there really isn't much different that I normally do.

Its not common for fish to die when using elevated magnesium to treat bryopsis. I strongly doubt it was magnesium.

I figure your problem is either in oxygenation, or water chemistry. Can you post your full parameters? Ammonia, nitrate, nitrite, Ca, dKH, Mg, etc. please?

No it's not, but it is common for fish to die when the magnesium level has a big sudden swing.

sorry for you're losses, but what are you're water parameters corrently? such as nitrate,nitrite, ammonia? also if you were dealing with that magnitude of a microalgae outbreak, I'd imagine you're dissolved oxygen level to be quite low, from all the activity of the microalgae.
