Lots of folks have chlorine in their tap water. Chlorine will kill bacteria. That is why it is added to the tap water to begin with. If you are using well water that hasn't had chlorine added to it you should be able to use it to clean your filter media.It doesn't make sense to only use pond water to clean a filter media, when no matter if I use water from my well, the filter will immediately be rinsed with pond water as soon as I put it back into place.
Can someone enlighten me?
Thanks in advance!
I do the same thing, but only 1 filter at a time over the course of a few days. The OP is probably using a hob filter so it's better to be safe than sorry.A lot of people go crazy with only using tank water on their filter media.
Just swishing around a sponge in tank water isn't going to clean much. People regularly post about their filters backing up, flow issues etc and I suspect they are using media that has never been properly cleaned.
If you have dedicated biomedia such as ceramic rings matrix etc that is never cleaned then it would be a good idea to properly clean a sponge under pressurized water like a faucet.
I clean two sponges under tap water and throw away and replace floss weekly with no lost tank cycles because I have dedicated biomedia.

Do you have a pond, I presume?
It’s better safe than sorry, your well water *could* have chlorine, so I wouldn’t.
You should only clean your filter media when it gets junked up anyway
