I got a Taylor K-2006 kit recently and tested the water yielding these results:
CC: 0 (no color change when I add the DPD Reagent #3)
I took a sample to the pool store today and got these results:
They said the low hardness was of particular concern and want me to put 25lbs of hardness in the pool.
I came home and tested again, and this time did Hardness as well and got the following:
My questions are:
1. Can their chlorine readings be that far off? and can I really have 0 CC?
2. I have never had a problem with Hardness before and I did the test twice to confirm the result. Can they be that far off?
My pool is clear and beautiful. I don't want to start dumping tons of chems in if i don't have to (and as I have done before based on their recommendations) I plan on adding Borax to bring up the pH and knock off the tri-chlor soon.
I have an at least 25-year old 25,000 gal in-ground plaster pool. DE filter and live on the central East coast of the US (PA).
