Water Testing

Liquid kits, strips, sample technique, reagent storage, and cross-checking suspicious results.

Digital Readers and Photometers

Use digital and photometric tools for repeatability when they are maintained and calibrated, and fall back to liquid testing when the result drives a real correction.

Run the test in the right order

Step-by-step Taylor FAS-DPD testing with the correct reagent IDs and sequence.

Translate the printout before you buy

Turn a pool-store printout into a retest plan, a dose decision, or a reason to ignore a bad recommendation.

Trust the result before you dose

Sample technique, reagent age, interference checks, and how to reconcile conflicting results.

Use strips as a screen, not the final word

Test strips work for quick screening but are not precise enough for dosing decisions.
