Clorox Pool&Spa Shock XtraBlue 1 lb

Bad quality

Works very well for my above ground pool. Because above ground pools are smaller, having the shock in a bottle, rather than a pouch is very handy as you don't need much product per shock. I just and, for the first time, the seller sent me POUCHES instead of the bottle. Notified Amazon and they made it right. Fortunately, I had kept my last empty shock bottle so I will just refill it. Shock pouches are for large pools that need a full pound (or more) of shock. Sellers: Please do NOT substitute the bottle for a pouch. There's a reason they sell it in a bottle!

I have a 16 foot above ground with a saltwater system and this pool shock is great for keeping the algea managed as well as opening the pool for the season. I also use it throughout the season as my pool gets used and starts to get behind keeping the water clean as storm water and wind brings things into the pool. Especially in late July as the water gets really warm this helps me stay on top of algae blooms and it has been effective for green as well as mustard algae both of which cause problems where I am. I just bought 10 for this season and it should last me through the season with plenty left over to open the pool next year. Great stuff and the before and after pictures are not fake, I had the same experience this year. I had a pool full of what looked like split pea soup when I took the cover off this Spring and put the shock in and hooked up the filter and ran it overnight after dumping one of these in and the next day It was crystal clear with just dead algae on the bottom to vacuum up. I use a whole one at the start of the season and about half for each shock every couple of weeks as maintenance. My pool is a 16 foot Summerwaves that I converted to an Intex filter and saltwater system.

Easy pool replacement!

I have used this product in the past and it's great. It is very easy to use and does a great job in the pool. But this review is really about the seller/shipper. They are rude, they lie and they lag horribly at getting you product to you. My was last in shipping. Instead of them sending another and that possibly get lost as well I asked for a refund and they lied saying that it was refunded but there was no confirmation. Had to speak to a customer representative for Amazon and they even confirmed that they had not issued a refund. Please don't waste your time and money with this seller. Find it elsewhere. Sorry for the long read.

The description shows this product in a bottle, it arrived in a pouch. I prefer the bottle, I do not use a whole pouch at one time. I have a small pool. I chose this seller because it showed the product in a bottle. Item works well
