Cyanuric acid is a stabilizer. **Q: How many tablets are in a 5pound container** A: 10 tablets. Basically $5.20 a tablet. **Q: How many come in each container?** A: Each tablet weighs approximately 8 oz. So in a 5# container, you should have around 10 tablets. **Q: Can I use this in my inflatable pool? Just wanting to make sure it won’t be too much since inflatables are much smaller compared to actual swim pools.** A: Actually this product/tablet is too large for a small inflatable pool. There will not be enough circulation in the pool to properly dissolve the product. It will not be cost effective for you. NOW, please know that we cannot recommend any product if your pool does not have a pump/filter. Assuming that you do have that, you will be better using a granular chlorine such as the HTH Pool Care Shock Advanced in the 1.5 or 5 pound container. This is because you will need a container that is reclosable and that you can measure the small amount (based on your volume of water) to your pool. Do not buy the 1 pound container of shock because it's meant for single use in a large pool (10,000-12,000 gallons). Again, the 1.5 shock in the reclosable container will work best. Please consider calling our Consumer Engagement Team at 866-484-7665 to get the exact amount of dosage needed for your pool. We're available M-F, 9 AM - 7 PM EST. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by T***E on June 8, 2026* These worked exactly as expected and made pool maintenance much easier.

They keep the water clean and dissolve at a good rate. They work great! Pair with Clorox pool tester steps to stay on top of chemical levels!
