Way to sanitize hot ponds/check bacterial levels?

[glassnumbers]

I guess there's a way to defend myself without also being disrespectful. Here's the respectful way then, Miss Mimosa. First, e kala mai ia'u. Second, I was wrong to insult you, even if you insulted me, that doesn't change the rules of aloha. Third, my line of thinking was "man, those hot pools have so much nasty bacteria caused by -human people- swimming in them, it can't be great for the little local critters. If only there was some way to cleanse it of that human contaminant." It turns out that the local critters don't care about the bacteria, so I was ignorant there. Fourth, I don't have any plans of flirting with local women, there's a reason why I explicitly said "hot tourists." Now, I am curious though. Why would it matter who I flirt with? Aloha is aloha.
