What size is your tank? What this of filtration do you have? And what's the livestock? This will give a better idea and help narrow down the problem

Before . And aqua tech filter 60 dual filtration. And marine land 400. Tropical fish.
Mollies
Plecks
neon tetras
Platys
Glo-fish
Corys

How many fish total in your 75G?

Also I haven't had great luck with cory cats in a tank less than a year established. I tried to test this theory with a 7 month old esablished tank and lost 2 out of 5.

You said you had the tank up to 86 degrees? Any particular reason? Thats pretty high for fish other than discus. Higher temperatures mean less oxygen in the water so suffocation is a possibility.

Could it be the painted "corals" are toxic ??? You don't have a lot of plants i think. If so it's almost impossible that No3 is 0 !!!!

If I read the info in the thread correctly, your fish died the day of and the day after a large water change. None since. Did all the deaths occur after the water change? Usually water changes will be helpful in most tank problems--in your case it appears to have caused it? Assuming you are on municipal water, my best guess is that there was a rainstorm around the time of your water change and your water district dumped in an extra big dose of whatever sanitizer they use. You just added your regular amount of de-chlorinator stuff--and it wasn't enough to handle the spike. Your most susceptible fish succumbed, the rest made it till some of the extra chemicals broke down and dissipated to the atmosphere. Just a guess. Personally I’m not a fan of the stress coat stuff, but that’s just me.

If you have the room/capacity to do so, if your can fit a large water container somewhere to allow your water to age out a bit before use, it might help to prevent the scenario I described above. The heavy duty BRUTE garbage cans work well. Add an air stone to speed up the process.

+1 on the nitrates at zero comment. My tap water runs at least +5. As an experiment, use your test kit to test your water straight from the tap.

Are the rest of the fish doing fine at this time? I hope you get to the bottom of your issue.
