Anyhow:

1. Read the Best Guess chart page, linked in my blue signature block. It answers the questions you are asking.
I have been going through the blogs & Tips and figured out that the "guidance" I was receiving from the pool store was WRONG. The latest test they performed resulted in a recommendation of using "brand name" Chlorine Neutralizer to lower my chlorine to 2.0 - 4.0 even though I have a CYA 100 or above. It's now obvious to me why I've been having a persistent algae problem.

I have the k2006 kit on order.

One of the things I find that is very cool is the Tips & Tricks on how to use the test kits. I think it's one of CarlD's tips to use 1/2 pool water & 1/2 distilled water so I can estimate my chlorine levels above the 5 ppm my DPD kit can do. Your recommendation to do basically the same to get a better idea of my real CYA level - something I would have never thought about.

A big thanks to you, and the other moderators & contributors! I now have a much better understanding of pool chemistry and look forward to not fighting my pool - but enjoying it.
