Good product, however the instructions included in the package are totally opposite of what is listed here. Also the shock has stabilizer in it which added to the overall CYA in your water. My pool holds 3,400 gallons (12’ diameter) of water so using any chlorine/ shock product with stabilizer on a regular basis will render the chlorine useless in a few seasons . Then it’s drain and refill the pool.

AlwYs use a start up kit prior to opening your pool. It aids the chlorine and clears any crazy stuff in your pool. Really enjoy using Amazon for this , I went to intheswim.com and found that they were a bit higher in price than Amazon.

Great value and clear instructions. My local pool place was ripping me off for years, glad I can now buy these chemicals on Amazon for a lot less.

Instructions on website (pictures of Step 1, Step 2, ….) are different than instructions included in box. Couple items are in different order. Which is correct?

Works wonderfully! I didn’t get my pool covered last year, so it’s sat all winter uncovered. We filled it back up with muddy creek water (it’s been raining). And this is what my pool looked like before and halfway through this treatment process! Literally 8 hours difference in these photos!

This kit offered a few things I needed. But it still missing alot to start up a pool. It's almost cheaper to buy everything you need separately
