I've had a big pool for 45 years. I've always used chlorine in large quantities to shock. People don't realize that if you don't shock with enough chlorine, you have wasted your time and chlorine. You can still end up with patches of green algae after shocking which means you still have combined chlorine in the pool leaving it unsafe without enough free chlorine to sanitize. This product is incredible. I started using it last year and it takes all the guess work out of shocking. It burns off all the combined chlorine and leaving behind all the free chlorine to sanitize. My water is like liquid diamonds. I have 10000 gallons of water and you actually need two bags a week for tolal effectiveness. Once on Monday and once on Friday. A little pricy but worth every penny to me. I have an autistic son that swims and puts the water in his mouth so I extensively test my water all the time, so I know for a FACT that this product gets the job done and my son is safe.

great results and chlorine free. Chrystal clear watt in no time. No harmful chemicals. Price is good too. We have been using it for three years now in our salt water pool.

This product has a straight forward chemical reaction in the pool water. It takes approximately 15 minutes for the reaction to complete. I normally run bromine in the pool but had neglected my pool for about a week so it was starting to get a slight green cast to the water. I started the pump and let the circulation get going good, used the recommended one pouch per 5,000 gallons of water. (My pool takes 3 pouches.) Sprinkled it around the perimeter per instructions. I let the filter (An old DE filter.) run for a few hours and the water turned crystal clear. I'm very satisfied with this product. Mike

This non-chlorine shock has a 5% higher concentration than the local branded shock and is cheaper even with shipping and the all-too-infrequent sale. Our pool water sparkles.

We use this shock in our 400-gallon hot tub. Since we cannot use a calcium-based shock, this stuff was called for. It eliminates ALL odors and cleans things up very nicely!

The granules dissolve quickly and seem to work extremely well. They don't appear to raise the ph all that much either. I will totally buy this again when we run out.

It cleans the water to a sparkly condition
Also, leaves a nice clean smell, without chlorine.
It works so well, that my pool doesn't need chlorine for a week.
