I'm interested in anybody's opinion on tossing indicator solutions into a pool or spa after completing the test. As a previous state bathing place inspector I was always taught (and I taught in my training classes) that is is rude to toss the test chemicals into the pool. After all, would you like if someone spilled wine into your pool? I complained to a local pool care company about their personnel who do that, and they just laughed, saying it has no effect on the pool. I disagree. What say you?
