Review: Seller is honest and reputable!! - Good product but the chlorine solution bottles were half empty when received. The seller refunded complete purchase price.
Review: Reasonably priced and accurate enough for daily checks. - This product is reasonably priced and is accurate enough for daily testing. I compared it my monthly testing titration kit which covers a lot more and find them very close in accuracy. This kit works best if you follow the standard testing procedures by using drops only from inverted bottles which assures uniform drop size and facing North when reading the results. I have found that different bottle angles and reading using different lighting makes the results much more questionable.

## Questions & Answers

**Q: Does it test for cya**
A: I use it to test ph and chlorine.

**Q: Tested our water and the cl side created orange bubbles when drops were added? 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.

### ⭐⭐⭐⭐ Good for the money
*by A***R on April 20, 2024*

Pretty good test kit for the money. Only issue is the colors that match the corresponding value aren't truly accurate to what you get after you test. Gives you a range and gets pretty close, but if you need to be very exact on your levels, you'll have to spend a bit more.
