Hot Water Killing My Platy's Or Nitrate Spike

[Platy lover]

My water is 85F in my aquarium could that have killed two of my adult Platy's and two fry? Or could a nitrate reading of 20 killed them? I am planning on doing a 50% water change tomorrow.

A tank I have with platies hits 84-85 F in the Summer quite often. I have yet to lose any.

I asked in another forum and we concluded it was ammonia

Platy Lover, if you can do so, reduce your water temperature. You are fully 10F too high for platy comfort. I have also seen fish survive extremes in temperature for a short time, as creeker said happens, but I do not place them in such a situation intentionally. If you simply maintain theem at 84F, they will die off over time, even if you can't pinpoint a particular death to the temperature.
Ammonia is quite another matter, and was not a part of your original question.

I re-tested everything and the ammonia was at 4.0

#32### thats high!

That is high enough to kill almost anything. Do an immediate 90% or larger water change and test again. You may need to do this twice.

I changed all of the water and it went down to 1.0

One more large water change and you should be there.

That is still too high, I'd do another large water change
