Swimming Pool Stabilizer and Conditioner | Water Balancer | Cyanuric Acid for Swimming Pools | Longer Lasting Sanitation | Helps Reduce Chlorine Loss Due to Sunlight | 25 Pounds

Wished it arrived the next day like the amazon page said it would, but I'll take it anyways. its a great product at a fair price.

Seems to work just fine.

Much needed to keep your pool in balance. Works well and water stays clear.

Good price — better than local and online pool stores. It raises my CYA levels by the amount I calculate it should, so I guess that means it’s good quality. Dissolving it takes a long time, but that’s the nature of the chemical, not an issue with product quality. I measure it out, put it in an old pillowcase, tie the top, and leave it in a skimmer for a couple of days.

There is no chlorine content. It is cyanuric acid which lengthens the life of chlorine in the pool. Loving in Georgia it is definitely required to keep the cost of chlorine reduced. This spring, I tested the pool chemicals after the water was balanced, I only had to add two pounds in a 30Kgal pool. A lot made it trough the winter so longevity was there.

Update one year later! Kept stabilizer in the original plastic bag and kept inside a plastic tub. The product remained intact!! Those reviewers who “dump” 25 lbs or mass amounts and say it doesn’t work are beyond clueless as how CYA works or should be added. I use Trouble Free Pool to balance my pool. As an example, my pool is 21,100 gallons and needed to raise my CYA from 50 to 70 to start the season. So, I added 4 lbs 6 oz slowly though a sock in the filter (per Pool Math) and left my pump on for 24 hours and do not backwash for a week. CYA does NOT register immediately - it could take up to a week! My point is, there is a specific method and measurements to guide you. Please don’t take advice or believe reviewers who apparently are totally ignorant of this product’s use. I am dismayed to see the price has almost doubled in the past year, but the efficacy of the product is unquestionable. Original review: Shipped quickly and a great price! Does not go bad so always purchase in large quantity and store in a plastic bucket! Happy customer!

Product was as described. Well packaged.

Took a lot to stabilize our pool because I never believed that these chemicals were doing anything. I just wasn’t adding enough. Before adding any stabilize first GET THE PH RIGHT. This is the essential first step.m Yes it might slow down your process but if you don’t it won’t work properly as well as other chemicals won’t work right either. If your Ph is really low, adjust it with Alkalinity Increaser so you aren't wasting product. Al of these products should be added a little at a time and when mixing always add the product to water not the other way around as a violent chemical reaction can happen as this creates a lot of HEAT! Adding to much to quickly will cloud your pool. I found out that by adding 2 lbs. in a 5 gallon paint straining bag (fine mesh) and place in front of a discharge port or possibly in the skimmer was the best way to do this. A little at a time. It may take a while. Don’t be in a rush.
