Decent but small vials

The testing accuracy seems fine, but the viewing vials are a bit small, making it slightly hard to see the color change in low light. Works best outdoors in daylight.

Reliable and affordable

Been using this brand for two seasons now. It's not fancy, but it gets the job done reliably. Just remember to cap the bottles tightly after use.

Clear instructions

I was worried about using chemical reagents, but the instructions were very straightforward. The bottle caps are color-coded which prevents mixing up the solutions.

Keeps my family safe

Peace of mind knowing the chlorine levels are safe for my kids. The reagents last a long time since you only need a few drops per test. Highly recommend.

Essential for pool maintenance

This kit makes checking my pool water so easy. The color comparison is clear, and the results match what I get at the local pool store. Great value for the price.

Good basic tester

Does exactly what it says. It tests pH and chlorine effectively. I wish it included a test for alkalinity, but for the cost, it's a solid choice for weekly checks.

5 FAQ

Q: Are replacement reagents available separately?

A: Currently, the reagents are sold as part of the complete kit. However, the standard dropper bottles fit most generic pH and OTO chlorine refills available at pool supply stores.

Q: The colors don't match the chart exactly, what should I do?

A: Ensure you are viewing the sample in natural daylight against a white background. If the color falls between two shades, assume the higher concentration for safety.

Q: Can this kit test saltwater pools?

A: Yes, this kit measures free residual chlorine and pH, which are critical parameters for both traditional chlorinated and saltwater generator pools.

Q: How often should I test my pool water with this kit?

A: For optimal water quality, we recommend testing your pool water at least twice a week during the swimming season, and always after heavy usage or rainstorms.

Q: What is the shelf life of the reagent liquids?

A: When stored properly in a cool, dark place with caps tightly sealed, the reagents typically remain effective for 12 to 18 months from the date of manufacture.
