Controversial Water test

[Keeg]

If you think that your water is too gross to drink, then you need a water change. This is obviously not true to some degree but there's some truth. Like if I had to, I would drink my fish tank water because I know it's clean enough for my standards.

even if it is absolutely crystal clear, im not drinking aquarium water. tons of tiny pathogens in there.

Crystal clear, non-smelling water could still have parameters way off and need a change. Unsightly water could be perfect parameter wise and not need one. Gonna have to disagree on using "drink-ability" as a way to tell when to change water. I don't see any truth to it and plenty of dangers. There's no need to invent some new method to tell when to change water when there's established methods like test kits or just observing your fish and plants.
