Clorox® Pool&Spa Swimming Pool Shock XTRABLUE® Plus™ Granules, Kills Bacteria & Algae in Swimming Pools, Swim-Ready in 15 Minutes, (12-Pack)

I just started up my pool. I haven't even had a chance to investigate what chemicals I needed to get it started yet. That night we had a heavy rain and my pool started to turn green. Not really knowing what to buy yet, I saw "6 in 1" and "kills and prevents algae" and bought it. I knew I needed to get rid of the green. I saw changes within 15 minutes of using it. After an hour the green was completely gone and my water was crystal clear. However it hadn't been green for long, but it impressed me about how quickly that green left. I'm going to give the rest of their products a try to see if it simplifies maintaining my pool.

this is my favorite shock! Considering I pay for a Walmart home delivery I rarely even go to the pool store for my shock . It’s such a good price and is $30 less than it is in my supermarket. I really prefer the liquid, but but this works very well and as long as you have something to stir it into the water, it dissolves easy enough And having it delivered for $40 is an absolute plus I have a 57,000 gallon pool so it’s very big but it only takes three of these if the water is clear and if there’s a lot of rain or I’ve been away on vacation, it’ll take four or 5 and within an hour the water is sparkling. Of course, my pool’s already mostly clear and clean. I don’t know how many it would take if you’re starting with a cloudy pool and dirty water. I imagine you would have to get a liquid. But this will be my go to

This pool chlorine takes out all the worrying about all microscopic bacteria that shows up pools. Use regularly as directed on package. Six super anti bacterial chemicals fight to keep your pool crystal clean. It's time to relax with Clorox on the scene.

I have been using this Clorox Xtrablue2 shock for my pool maintenance, and it performs beautifully every season. The 1-pound bags are perfectly portioned for my pool size, and I love that the formula dissolves almost instantly without any pre-mixing. It tackles cloudy water overnight and keeps green algae completely at bay without bleaching my vinyl liner. It keeps the pool sparkling blue, and the built-in clarifier saves me from buying extra chemicals. Highly recommend keeping a 6-pack on hand!

This is a fast efficient product that you can trust to clear your pool water and get up and running in just one day. I use 2 to start and another if the water still has a tint to it. After that 1 a month if it is a light load or no use and 1 if I have a heavy load or a lot of rain.

Easy to use. Nearly always takes care of my shocking/ algae needs without have to buy additional chemicals (algaecide) or lug huge tubs of liquid chlorine. It doesn't work on mustard or yellow algae, so I'm giving it 4 stars. I have to buy additional chemicals for that.

The tablets were not individually wrapped which causes fumes. And harder to handle. A number of them were broken and not usable. Disappointed.

They did not send me Clorox. They sent me a generic and that's makes a big difference for my swimming pool so I'll need to

Even if you purchase this product, it will not be delivered — the order will be canceled. My order was canceled well after the expected delivery date. I recommend that you avoid buying this item if you need it in a timely manner.

Initially this product appeared to work but imagine my surprise when my filter would no longer work and I had to buy a new one. When I took the old filter out it was full of this product. It was unmistakable b/c of the blue color. I'd ask for a refund if I could. Do not use.
