Rx Clear Swimming Pool Stabilizer and Conditioner | Water Balancer | Cyanuric Acid for Swimming Pools | Longer Lasting Sanitation | Helps Reduce Chlorine Loss Due to Sunlight | 1.75 Pounds

This 25lbs would cost at least twice this much at Pinch yer wallet. Great buy, and the seller shipped super fast. I've had the first dose of 5 lbs in my pool a few days, and after testing it's definitely the real deal, and will help keep my pool blue all Summer long.

Have been using this brand for years in my salt pool. No issues other than price jump like everything else but this is the best deal on the market.

Arrived on time. Works so I don't use so much Chlorine.

The stabilizer is fine grain, not clumpy. Works great on my pool.

Wonderful product

Arrived fast. Bulk version of what pool store sell.

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!

Works great
