Essential for pool owners
This kit is incredibly easy to use. The color chart is clear, and the drops mix instantly. I test my pool water twice a week now, and it gives me peace of mind knowing the chemical levels are safe for my kids.

Clear results every time
I love how distinct the color changes are. Even in low light, I can tell if my pH is off. Much better than the strips I used to use which were always hard to read.

Perfect for hot tubs
I bought this specifically for my backyard spa. It fits perfectly in the cabinet, and the instructions are straightforward. No more guessing if the water is balanced!

Good value for the price
Works well for basic testing. The plastic case feels a bit lightweight, but the reagents seem accurate when compared to my local pool store's digital tester. Great for routine checks.

Reliable and fast
Takes less than two minutes to get a full reading on chlorine and pH. The comparator block is sturdy enough. Would recommend keeping it indoors when not in use to preserve the reagents.

Decent but caps leak slightly
The testing accuracy seems fine, but one of the reagent bottle caps arrived loose, causing a small spill in the box. I secured it with tape, and it works okay now. Just check the seals upon arrival.
Q: What do I do if the water sample turns cloudy after adding drops?
A: Cloudiness usually indicates high calcium hardness or the presence of other contaminants. Ensure you are using fresh water from elbow-depth in the pool. If it persists, consider testing for total alkalinity and calcium hardness separately.
Q: Does this come with a carrying case?
A: Yes, the kit includes a durable plastic comparator block that doubles as a protective case for the two reagent bottles, making it compact and easy to store.
Q: How often should I replace the reagent bottles?
A: For best accuracy, we recommend replacing liquid reagents every swimming season or within 12 months of opening. Always store them in a cool, dark place to extend their life.
Q: Can this kit test bromine levels as well?
A: This specific kit is designed for OTO residual chlorine and pH testing. While OTO can sometimes react with bromine, for accurate bromine readings, we suggest purchasing a kit specifically labeled for DPD or Bromine testing.
Q: Is the color chart easy to read for someone with color blindness?
A: The color gradients are standard for the industry. While we strive for high contrast, users with color vision deficiencies might find digital testers or assistance from another person helpful for precise matching.
