Why would it not mix in like the ph side?** A: Never seen this happen. The OTO reacted with something in the pool. Was the pH way off? Try testing your tap water with OTO. If it's chlorinated, you should see a light color change and no bubbles. regardless, I would check with a pool maintenance shop. **Q: Does it test Cya levels in the pool?** A: No, you need a good test strip or pool supply store to test your water. **Q: How can tests can be ran with this kit?** A: Easily. Dunk the apparatus down into the pool water and fill both sides. Pour a few drops from each side then add 5 drops chlorine reagent to the left side then 5 drops ph reagent to the right side. Cover the openings with the provided caps, mix, then compare colors of the water to the colors on the container. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Small Test kit for a SMALL pool *by A***R on August 18, 2023* I really like this above the test strips I was using for my 8x30 Intex Easy Set Pool.
