all fish started to breath heavy
and they would sink to the botton and die they started to look like if they had a white film
could it be Brooklynella does it happen that quick?
corals look good so far
Besides a water change should I do something else?
Can fish get disease from plants?
thanks

sounds like not enough oxygen did you turn the lights to a minumum that could have an affect did the ph drop just a little as well
if you tried to turn the lights off for longer to deal with the algea bloom the lights can consume the co2 maybe if you had lights on for not as long caused a build up of co2 and with that many fish in the tank not enough oxygen fast enough can kill them.
I only say loss of oxygen cuz you say all other perameters check good then your fish were breathing heavy.

I had the exact same thing happen to my tank a few months back. I lost it all. I had the same kind of experience. I did nothing abnormal to the tank nor added anything new. All my fish were suddenly gasping for air and trying to swim to the top. I did everything I could but lost them all in 24 hours and lost my corals a few days later. My ph and everything was right around normal. I feel for you though. I'm just now cycling the tank again to start over. Good luck to you.

Can't see a disease that would kill that fast occurring since the last fish you added a month ago. Is it possible that the food was contaminated?
What kind of circulation do you have in the tank?

Also ANYTHING that could have gotten in the tank...any cleaners, painting, etc anywhere near the tank? Anything on your hands, etc? Any recent water changes or top offs, etc? Gonna need to really think hard on this one (including if you have any kids who may have put something in there).

I belive he lowered his lighting down and the exess co2 build up made it hard for them to breath same thing happened to me to deal with hair algea in my trigger tank and my fish were breathing heavy then I added an air pump then within a few hours they were breathing normal and swimming normal
