Just like humans, koi can survive in some kinds of dirty water for short periods of time, but they’re unlikely to thrive. Also like humans, there are certain types of pollutants that can prove to be deadly within very short periods. The difference is that we humans cannot directly see the kinds of harmful pollution that stress koi or even those that kill them outright. Besides, if you’ve invested care and money into your koi pond, it only makes sense to provide them with the best environment so you can enjoy bold, bright colors and lively, energetic fish that aren’t struggling to survive.
