Liquid Test Kit vs Pool Test Strips: Which Is Accurate?
Pool liquid test kit vs test strips compared: accuracy, cost per test, combined chlorine, and which you need for real problems.
The short version
A drop-based kit gives numbers accurate enough to dose from, and a FAS-DPD kit is the only practical way to measure combined chlorine, which is what causes the chlorine smell and stinging eyes. Strips are fast and approximate. Own the liquid kit for real chemistry; use strips for a quick check between proper tests.

Choose the Taylor K-2006-SALT FAS-DPD Kit if…
You want to know how much chemical to add rather than guess. A FAS-DPD kit measures free and combined chlorine separately, and combined chlorine is the number that tells you whether the pool needs shocking, which no strip will tell you.

Frequently Asked Questions
Why does my pool smell of chlorine if chlorine is low?
That smell is chloramine, or combined chlorine, which forms when chlorine reacts with sweat, sunscreen and urine. It means the pool needs more chlorine, not less, which is the single most common misunderstanding in pool care.
What is shocking and when do I do it?
Raising free chlorine sharply to break down combined chlorine, usually when combined chlorine rises above roughly 0.5 ppm. Our shock dose calculator sizes it for your pool volume and current readings.
Do strips go off?
Yes, quickly once opened, especially in humidity. Keep the bottle sealed, never wet the desiccant, and replace them each season rather than using last year's.
