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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/43922912-u-s-pool-supply-standard-3-way-swimming-pool-spa](https://www.desertcart.hk/products/43922912-u-s-pool-supply-standard-3-way-swimming-pool-spa) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-09-13*
