Reagents for - Pool Lab, PoolWaterLAB, Water Tester (Alkalinity-M Photometer)

The Reagents I have tested so far have been consistent and pretty close to "professional" pool testing companies.Those I have tested with PoolLab1.0 are:CYA - Cyanuric AcidPhenol Red - pHDPD1 - Free ChlorineDPD3 - Total ChlorineAlkalinity - AlkalinityI have ordered Reagents for Calcium Hardness.

Works perfectly !

Don't let the box fool you - there are NOT 50 tablets in this box - only 40 now come in the box (box is smaller too so not an accidental packaging error) would be cheaper to get the multi-box

I had been struggling with balancing our new spa using the test strips you typically buy. To ease my mind I decided to order the Pool Lab 1.0 to get a digital readout I could use to adjust or 2,000 gallon spa appropriately. I have purchased the Calcium Hardness liquid reagent, pH, Alkalinity, Total Chlorine and Residual Chlorine Reagents. They all work great and have allowed me to get our spa balanced with ease.I noticed the sample pack of reagents that came with the Pool Lab 1.0 were hard and more difficult to get crushed but the individual 50 packs seem more "fresh" and have crushed with ease allowing me to test the parameters quicker and not have to spend 5 minutes trying to get the reagent tab to dissolve.This is definitely going to become a reoccurring order.

Takes to long to do all the test
