Rx Clear Calcium Hardness Increaser for Swimming Pools, 8 lbs

I chose to buy from this website because it was cheaper than 2 other major companies. I'm not sure if this is the reason but the chemicals come in a plastic bag in the cardboard box. I think this is a fantastic idea; I have a lot of buckets from chemicals that become plastic waste so not having it in a bucket is great. Otherwise, the chemicals are the same as from any other company as far as I can tell.

Great product and easy to use.

This is excellent for removing excess moisture in your home…We live in an old farm house that had a musty smell ….I saw a video on how the Amish ppl use this … It really works….put some of this in a cloth bag ….. hang it over a container BC it will drip ,drip ,drip, removing moisture from the air…. NO MORE MUSTY SMELL !!!!! YEA!!!!!

Great support

Product arrived in 4 days of order being placed. Well-packed with usage instructions and first aid instructions clearly labeled on box. I have ordered this product previously, and it works well, and is very well priced.

This product works Easy to use, good directions to follow. Have purchased product twice already. Great value compared to other comparable calcium products.

Read the instructions. Dont use more than recommended at one time. It got very hot in the mixing bucket.

Have been using for the last 9 years

Mentioned earlier in survey

Box contains a plastic bag full of pool chemicals. Box was not handled with care. Fund box on my doorstep with impact damage. The interior bag was torn at the same spot, resulting in the chemical leaking out of the box. Whether this is how the product was at the Walmart store, or this is how the Walmart delivery person delivered it, Walmart is NOT the place to online-order bulk pool chemicals.
