I was always under the impression that Koi were relatively dirty fish..
Do they need particularly clean water to survive?

No, there was some bollocks about you had to leave tapwater standing out overnight or something before using it
fuck knows, it was over 25 years ago

leaving it standing will allow any chlorine to evaporate
but it's not as if fish will be killed by an elevated level of chlorine for one day
it's a problem with biological filters though, things used to treat harmful bacteria in tap water will also kill any beneficial bacteria in the filter

they don't need clear water, but they do need clean water
they'll tolerate a wide range of pH, but not rapid changes in pH, high levels of nitrate and nitrite will kill them, as will ammonia at very low concentrations
(used to have some, but they got too big and had to rehome them)
