Nothing worked like this All mold and traces of mold gone Easy to use Be careful not to use too much Amazing results

very good

Used for my above ground pool 6'X9'52" and water fountain. Clears water very quickly. Only small amounts needed. Just make sure item is sealed or will rust any nearby metal parts and cabinet.

After a freak storm damaged my pool last summer I purchased a new pool this year and knew after the pain my previous pool was too keep clean off algae I needed to find something more than just chlorine tabs to keep my new pool clean and hopefully to last at least until my teens are grown. I'm so glad I researched and purchased this pool shock. Every few weeks when I notice the grime building up I just dump a bag in, use a net to stir it up a bit, and by morning it's clear again. I've gotten quite a few compliments on how clear and clean my pool looks. I also love that it came with pH strips which is helpful too. Only complaints are that even after stirring and having my pump running 24/7 there's particles clumped and settling at the bottom of my pool and it's so hard to clean up. (Not sure if I'm doing it right.) Second is that it's a bit pricey for what you get but what can we expect in a chlorine shortage in pandemic times? Hopefully the costs will go back to normal once things settle because this is a worthwhile purchase but not if it ends up costing more to purchase than paying someone to maintain for me.

Just enough for a smaller pool. 12 foot by two feet deep. Only bought 1 for the whole season. Always use by your gallon size for correct amount. We only used a few spoons!

Put it in Thursday evening before leaving on a weekend trip. Came back Sunday night to a clear pool! I adjusted the pool filter timer to go off more frequently but otherwise it did all the work!

The good news is that it is shock that appears to work as well as any other chlorine-based shock. The problem is that the description is for a 1 lb package but it is actually just over 13 oz. So the good price quickly evaporates if you consider the price per lb. Hopefully the vendor will correct this error since it is otherwise an OK product.

Standard shock treatment and use it for our decorative yard well-pump's underground water supply. After a while the water develops a rotting smell from the heat and algae. A small application of this shock treament does the job of getting rid of the alfae and the smell.
