your cities water treatment plant should be more than capable of cleaning out those chemicals. it's really just a problem if you're a lab that does it everyday.

No silver ions are kind of bad for waste water treatment. Amounts few hobbyists can flush are likely harmless (and more would be too valuable in silver to flush) but still you should collect used fixer and bring it to consumer chemical waste collecting place if that kind a thing exists in your location.

this but unironically, if you live in a large city the local water plant probably has more problems with everyone's cooking oil going down the drain than your tiny amount of darkroom chemistry

It is a derivative of a meme from /ck/ that has become popularized across other boards, where pouring melted fats down the drain, which inevitably causes the pipes to become clogged, is often done to spite landlords for perceived slights or a general disregard for behaving in a civilized manner.

How do I do this in a way that doesn't kill me like I'm making crystals off of /b/?
I'm not too keen on dealing with halides, as they can be fairly nasty at times.

This lol people think that when you see something go down a drain it just instantly goes into the ocean.
