Reagent 3 2 oz R-0003-C

Have ordered before with no problem. The last order rec’d in April doesn’t work at all. Unfortunately. I tried it after the return date. After a couple of weeks of my pool looking and smelling worse each day, I bought a new bottle at my local pool shop. That one showed a high FC, while the 1 from Amazon still showed 0 from same water sample.

This will be used in a condo community that must follow Pa. commercial pool regulations for daily chemical testing. Able to buy the exact size and type of pool chemical testing product instead of buying cabkit with products that provide no value.

Taylor makes the best reagents for getting accurate levels of your pool. This came quickly and was great in replenishing my supply. Thanks

Good replacement reagent. I don't use much of this one. I go for a bigger size on the main dpd and ph reagents and refill my smaller bottles.

As advertised, great produced, super-fast shipping.
