Taylor Technologies R-0871-E FAS-DPD Titrating Reagent, 16 oz, Liquid

Great value, especially when SLAMing. Says it expires after a year, so this much may not be needed for everyone.

Does what it’s supposed too and cheaper then the spa shop

I follow the TFP (Trouble Free Pool) system of care for my pool. During the SLAM process (Shock, Level, and Maintain), there are many FC tests to maintain liquid chlorine at sanitizing levels. This is the regent used for the FC test. The size of this bottle of R-0871 reagent has been wonderful, as I have filled my smaller bottle that came with my Taylor test kit several times.

Same stuff as the little bottles. If you check your chlorine levels often, like you should, this will last a year and save you money. Just pop the top off the little bottle and use this to refill it. Purchased a few times and the expiration date has always been fine.

This was so much more economical than buying the smallest bottle from the pool supply stores. You’re also insured to be getting the highest quality Chemical I have always used Taylor products for my swimming pool and have never been disappointed with the results. They are clearly the top of the line supplier for swimming pool Test Kits for the homeowner. by direct from Taylor and save!

Here in SF Bay Area, I tend to keep my pool uncovered and very warm during the summer. But that means lots of chlorine loss. Even with salt water generator, I like to do lots of testing. This bottle makes the FAS-DPD testing more affordable. I keep the unused portion in a wine fridge at 58 degrees F and in a dark part of the fridge with no light entry. I then refill my 3/4oz drip bottle when needed. So far, this regent has lasted 3+ years without any apparent degradation. Towards the end of a bottle, I will compare test results with a new bottle, and they are identical. Same for cyanuric acid reagent which also lasts over 3 years if properly stored.

I compared this to a sample test at a pool supply company (not the store chain but a pool comtractors) and it matched the same so legit!

Took a while to arrive from the US, but worth the wait and cost to have this reservoir of FAS-DPD titrant on hand. Dropper top of the standard 2oz bottle removes and replaces easily to allow refills from this large bottle.

Arrived as described. Simply refilled my existing small drop container.
