The best pool test strips for clean, hygienic water

Monitoring chemical levels is an important part of pool maintenance as it’ll help you make sure the water is safe to use. It’s essential you get the chlorine, pH and alkaline levels right before going for a dip – although many pool test strips measure extra elements like bromine, salt and iron.

While pool test strips are a quick, easy and inexpensive solution, you could use more costly liquid test kits for more accuracy, or choose a digital tool with an easy-to-read screen.

What is the best way to test pool water?

Start by measuring the chemicals at least once a week – and be sure to take readings from both ends of the pool. You may want to test the water up to three times per week during spells of hot weather and after storms.

Most pool test strips give you results in seconds after you submerge them, and you can compare the coloured markings to the ‘ideal’ results provided on the bottle. Then, adjust the level of chemicals in the water accordingly.

It’s worth keeping track of your test results in a log book or mobile app, as it’ll help you get to grips with the chemical fluctuations and better predict future changes.

LaMotte Insta-Test Strips

LaMotte is a popular brand when it comes to pool test strips, and it’s been around for over a century. The company sells a range of different chemical measuring kits, so you can choose the number of elements you’d like to track. The Insta-Test 3+ will detect free chlorine, as well as bromine, alkalinity and pH, while the 4+ also measures the water’s total hardness.

For an even more detailed water test, try the Insta-Test 5+ or 6+. You’ll get 50 strips per pack, which provide instant results. According to LaMotte, there’s no chance of cross-contamination between the color pads, so you’re guaranteed stable results.

Clearwater Dip Test Strips

Another customer favorite are the Clearwater dip tests. Providing three measurement results, these strips keep things simple; you’ll get pH, chlorine and total alkalinity ratings.

Once you’ve dipped a test strip into the water, just hold it horizontally and check the colour-coded results against the chart on the bottle.

Unlike many pool test strip kits, AquaChek also measures the level of cyanuric acid (stabiliser) in the water – an important factor for outdoor pools, where UV rays affect chlorine dissipation. It also measures the main three elements: free chlorine, pH and total alkalinity.
