Clorox Pool&Spa 12004CLX Chlorine Stabilizer, 4 lb, 4lb

Does what it’s supposed to….increases CYA and makes my chlorine last longer. Good price and does what I need it to do. Despite the instructions, DO NOT ADD THIS PRODUCT TO YOUR SKIMMER BASKET! And definitely do not pour it straight into the water. These are larger granules and take longer to dissolve than other pool chemicals. Put it in a sock, tie it with a string (make sure it is strong enough), tie it to something so it dangles right in front of the jet return where the water comes out and squeeze the sock occasionally. This took me about an hour but may take longer depending on the amount and frequency of squeezing, LOL. Yes, it sounds weird, but it works. Google “cya sock method” for more info.I needed to increase my CYA from 30 to 40 ONCE AGAIN due to all of the rain, splash out from swimming, and adding hose water every other day due to evaporation and some slow leaks. This stuff does exactly what I needed it to do, and that was raise my CYA level. Now my pool holds my liquid chlorine (which does not contain any stabilizer, unlike chlorine pucks) and makes it last much longer so I’m not going through 4 gallons of regular bleach every week!I recommend this product! Just make sure you have a reliable testing kit to check your CYA levels and I do not recommend using this product if you are using chlorine tablets (trichlor) or other forms of stabilized chlorine (dichlor aka “shock”) which already contain stabilizer in them and will cause your CYA to get too high, which causes BIG problems – but that is a discussion for another day! Happy swimming, y’all! 🙂

Granulated Cynauric Acid. Our pool was using a ton of chlorine. Foolish me didn’t realize how quickly it dissappears without a stabilizing agent. Added the appropriate amount and chlorine has been lasting much longer.Get you a good test strip kit. Do some basic research on pool chemicals and balance. Understand what each component does and why it’s needed. Use an online calculator to get you the right ratios for your size pool. After doing that, you should have a relatively clear pool. Also, stop peeing in the pool.

Quality pool stabilizer delivered to your door. I save about $5 buying this stabilizer from Amazon prime. Why pay more at a pool store!

Good product, but use with caution. This is a good product, but be careful when using it, and only add a limited amount at a time. If you’re conducting a CYA test and the result is less than 10, don’t assume you’re at 0. Try adding 10 PPM at a time. It’s much easier to do this and stay safe than it is to exceed the limit and be forced to drain your pool. If you’re using chlorine pucks, be aware that these pucks also add CYA to your pool. If you notice your CYA levels rising too quickly, stop using pucks and granular shock, and start using highly concentrated chlorine bleach as an alternative, which is sometimes branded as liquid pool shock. Bleach is alkaline, which will cause your pH to start rising, but lowering your pH is a much easier task than lowering your CYA, which, again, requires draining your pool proportionally.

Sunscreen for your Chlorine. Great price and super effective to protect your pool’s chlorine. This product acts like a sunscreen for the chlorine so the sun doesn’t burn it away. Dissolves very fast and mixes with the pool water to ensure it helps stabilize your chlorine’s level. Remember to add more when you do a filter flush!

It’s okay. It worked okay but it didn’t dissolve well.

Works great. Much better value than what they sell in pool supply store!

Works great. Got our pool back in balance and we were back in business.

Great. Great value, great results and will be repurchsing. Price point less than local pool store.

Good quality. Very effective Disolves relatively easy
