Clear instructions
Even as a new pool owner, I found this very easy to use. The color chart is distinct, making it hard to misread the results. Highly recommended.

Decent but basic
It does the job for basic testing. The plastic feels a bit thin, so I handle it carefully. The reagents seem accurate compared to my local store test.

Reliable results
Been using this for three months now. The reagents haven't expired or changed color prematurely. A reliable tool for keeping water safe.

Simple and effective for weekly checks
This kit is exactly what I needed for basic maintenance. The color comparison is clear, and the bottles are leak-proof. Great value for the price.

Essential pool accessory
I keep one of these by the pool at all times. It helps me adjust chemicals before guests arrive. Fast shipping and well-packaged.

Good starter kit
Works well for checking chlorine and pH levels quickly. I wish it included a tester for alkalinity as well, but for the cost, it's a solid choice.
Q: Is this suitable for saltwater pools?
A: Yes, this kit works for saltwater pools as it measures the free chlorine residual, which is present regardless of how the chlorine is generated.
Q: Can this kit test for bromine levels?
A: No, this specific OTO kit is designed only for testing pH and residual chlorine levels. We offer separate kits for bromine testing.
Q: How often should I replace the reagents?
A: For best accuracy, we recommend replacing the reagents every swimming season or if they change color before the expiration date printed on the bottle.
Q: What do I do if the water sample turns dark purple immediately?
A: A dark purple result usually indicates extremely high chlorine levels. Please dilute your water sample with distilled water and re-test, then multiply the result by the dilution factor.
Q: Does the box float if I drop it in the pool?
A: The box is made of dense plastic and will likely sink if filled with reagents. We recommend keeping it on the pool deck during testing to avoid loss.
