    This stuff works great! I used to get it at Leslie's but didn't have time to run out this week so I was going to grab a few bags on Amazon to get me by. Turns out this seller has it for a LOT cheaper than the store. This normal price matched the 30% off sale Leslie's was having! Got here fast too.

    With a pool, it seems we are always tweaking the water. Works as good as any other product.

    If you notice a lot of the products, whether shock or others, look who actual makes it.

    Typically the same company and they make batch runs for each distributor. Same stuff, so I go for the best price.

    After shocking our pool over and over this past summer and not having it fix the algae problem, we switched to this brand and it worked wonders. Cleared up all the algae and was able to sweep it right off the next day and didn't have to shock the pool again the rest of the year. This will be our go to shock from now on.
