breathing heavily after water change?

Start out by using your aquarium test kit to test the tap water for pH, ammonia, nitrite, and nitrate. Write down the readings and post them here. While you're waiting for test results, tell us about the tank. Size, filtration, substrate, and stocking would all be helpful.

Nitrates abit higher than normal but that's not enough to kill your fish instantly, even with Nitrate over 80ppm still not kill your fish that fast. There must something going on with your tap water. There 2 things that able to kill your fish instantly are 1) tap water temp way to different than your tank water, 2) PH change suddenly drop too low or spike up too high. I'm more clean toward water temp sudden change that kill your fish (remember each fish react to water parameter change and act/ajust to new change differently)
 
Tap tested
7.0 pH
0 ammonia
0 Nitrites
5 nitrates

I use the kitchen faucet to get the temperature right when filling up. I could of been off but usually I get it as close as possible by touch. I have 5 tanks I water changed today. I never have problems until this past week. My dat which is in another tank is swimming very oddly and swimming in the air bubbles gasping. I added aquarium salt to that tank but I have for the last 3-4 water changes. I did a extra 25% water change just in case it was me adding too much salt.

Call your municipality and ask about chloramine being added to the water. Chloramine levels can swing in municipal water. At least now you know your base line test results for your tap water for future reference.

Water temperature, as long as it is close, shouldn't affect the fish. How much Prime do you use? It is a reducing agent so it theoretically can reduce oxygen levels when drastically overdosed.

A capful treats 50 gallons so the 50 gallon tank is very easy to measure out.

I'm sorry if you felt I was insinuating you overdosed your tank. I'm just going through process of elimination. I am thinking it's a chloramine issue. The symptoms sound as such to me.

No it's a very valid question. I wasn't insulted. I appreciate you help. Ruling out what it's not is the best way to figure it out. I will try to contact the municipal, but I don't even know how to find that number or who to call or what to say

Look up the water authority for your area. You can find this info online sometimes at the municipal website.
