It's great that you and your cham trust each other as you say, but it seems you have the inability to accept the fact that the chemicals in the water meant for human use Is probably not the best for a chameleom. It's amazing how they can swim, no doubt. However, it gives the wrong idea to many of the future viewers on YouTube.
I'm not trying to put down what you do, but I also don't condone this kind of behavior. It reminds of the videos of slow lorises being tickled and cuddled... Can they be house pets? Yes... Shoudk they be pets though? Probably not. When videos of cute slow lorises go viral, everybody wants them.... Demand goes up and people take care of an animal inadequately and have false beliefs on proper husbandry. We're not making drama for you, and we're certainly not trying to put you or your cham in a negative light.
People on here mostly just want to give their input and help. Maybe we don't have the best ways of saying things in a nice way, but you have to understand that some may see what you're doing as something that is unacceptable.
Best regards,
