I believe you, as you have a lot more experience with this than I do, but I kept retesting each sample multiple times and it did seem to take more drops if I used more. I would drop, swirl, drop swirl, drop swirl, etc. Is it possible that the harder you swirl could cause a variation in the number of drops (as in maybe in some test I did not swirl it hard enough before putting in another drop)??
Thanks for all the help. Here are a few questions that I asked earlier in the thread that were not answered yet. If anyone knows the answer to these I would greatly appreciate it.
Wouldn't the CC be rising if there was bleach eating the algae? Or am I keeping that "at bay" due to the fact that I keep adding bleach?
My pool has a green tint, but the walls and bottom of the pool are not slimy at all. The green tint was there as we were filling up the pool. Isn't that odd?
Also, when I put the water in a clear plastic cup it is clear water, no green. So wouldn't that suggest the the algae is coming from the walls and bottom? But like I said, they are not slick at all.
