Clorox Pool&Spa Shock XtraBlue+ Granules Swimming Pool Shock, 1lb for sanitization

This is hands-down, the best shock treatment for a pool. It works super fast and makes the water really clear and blue. It doesn't leave the water with that cloudy look that a lot of other ones do. it cleared my whole pool up within a few hours.

I have written a detailed review three times now, and each time the Walmart app goes back to the main screen and it is blank when I return. So I'll just say that it turned the water clear. That's it. Fix your app, Walmart.

The great thing about this pool shock is that everyone can swim shortly after! It's awesome when you have anxious kids that swim every day. Need to follow instructions and use entire bag. Careful not to breathe in the dust! It's crazy strong! I always add a little fresh water to our 10 foot pool just to dilute it a little. But it will immediately clear it up, especially if you use a clean mop or broom and sweep all sides and bottom.

My large above ground pool was icky green after lots of rain and. lots of leaves blowing into it. We were gone on vacation for a week and came back to a green pool! Treated it with this shock product and overnight, the pool was clear! Recommend checking pool pH after to determine if you need to add baking soda or something else to correct pH after shock.

This product is amazing! We're still learning how to maintain a pool, this product has helped with that learning curve. It absolutely works as described; it brings pools back to life, acting as a stabilizer for pool chemical levels when necessary and a shock to eliminate gross, foggy algae residue. Just so you know, if you have an above ground pool make sure the pump is on when distributing the product, there needs to be moving water to dissolve the product otherwise the crystals will drop to the bottom and discolor the pool. The instructions on the package are clear.

Whether you're opening your pool or cleaning it up or leveling off chemicals, shocking is a necessary Process. always read the package To get started , do not dissolve in a buckett it's actually in the instructions And it will not work as well.You need to broadcast it across the pool.I do it slowly around the whole pool , especially in the deeper end Then I stir and brush.The brush might be an hour or two later , though. It does a good job

This is actually spa shock but I have a 6x10 21 inch deep popup pool. Perfect size for opening it for season ( a little stronger than needed but) then I just use small tablets in a dispenser to keep it up. Definitely a clean pool for unfiltered water.

I've used this before %26 bought it a few times since. It works good.

This worked really good on our 18ft pool most of the summer but towards the end it stopped being as effective. Maybe we did something different but I don't know what it could have been.

These are awesome for our above ground pool . Do it in the morning and it's ready we know it's extra good when the kids want to get in late afternoon. Price is just a little high like most things but it is worth it for the consistency
