All I've added to my tap water during water changes is prime during the last 9 months since re-entering the hobby. No water quality issues at all. Only deaths were from a feisty firemouth and bad stock from LFS.
You only need to add Tap water conditioner (de-chlorinator) if your water parameters are good and it's just a regular weekly change. Less solutions the better unless absolutely necessary.
I agree with the above. Stress coat is a good dechlorinator but stress Zyme is definitely not needed. Personally, add as few chemicals to the tank as possible.
