R-0009 reagent review
Love that this is a bigger bottle than the one that came with my test kit! Mine has a 2021 expiration date (more than enough for me because I go through this one fast!) and works perfect for testing the total alkalinity in my pool water. No complaints here! :) Simple, easy purchase with free Prime shipping. Recommended! P.S. For most accurate results, wipe the tip of the bottle with a damp cloth or paper towel between each drop.

Exact replacement for the R-0009C in the Taylor K-2006C test kit
I use this to measure total alkalinity. I use the Taylor speed stirrer with it as well. My pool has never looked better and I routinely measure pH, chlorine, total alkalinity and CYA levels and this one works great for TA levels. One bottle 60ml (this size) lasts almost a year, so having an expiration date of at least a year is good. If I need to raise the Total Alkalinity, I just buy the 13.5 pound Baking Soda bag that can be resealed from the local cost co which is a lot less expensive than the various pails at the local pool store called pH up

Good value for the money!
I use this product for my pool. The 2 ounce size is the real plus. Pool test kits come with 3/4 ounce. Expiration date was 7/24 which is another plus. Overall I will purchase from them again.
