It only matters in that well water doesn't have chlorine or chloramine, like city water does, which is better, but I've heard it can still have a some amount of heavy metals, and sometimes a lot of nitrates, so adding conditioner is still a good idea, unless you get the water tested for everything it could possibly have, and it doesn't have anything harmful in it.
Keep performing multiple large water changes (like, 80-90%) until you can get Stability and Prime. Once you get those two, you can relax a little with the water changes and just follow the instructions on the Stability bottle. Still keep dosing with Prime though, to lock up the ammonia and nitrites, which are harmful to fish.
With good water quality and some salt, those Pacu fish will heal up in no time.
