Not all that funny, to me.

When I started PoolSolutions.com (1996) there weren't any such stores that I could find. I couldn't afford to trademark it, so that's what I get.
It's especially ironic that a store using my name (unless they started before 1996) would be opposing the BBB method. Ugh.

OTO is a chemical (orthotolidine) that turns yellow in the presence of chlorine, and is used to make cheap and reliable testkits. You can get an OTO / phenol red kit at Walmart, usually.

Please do so.
