Clorox Pool&Spa Alkalinity Increaser for Swimming Pools, 5 lb Bag, Granules

I love this stuff! Use it alllll the time w this Florida sunshine! It works fast and it's very effective! A little goes a long way and so worth the money to have safe and stable pool levels!

worked good to increase alkalinity as the pool maintenance person requested. I've always heard this brand wasnt effective but this worked great for what its intended for

Product was easy to use and seems to be as good as any. It also was more affordable than buying from a pool supplier.

I needed the Clorox Pool%26Spa Alkalinity Increaser for Swimming Pools, 5 lb Bag, Granules and it was advertised at a great price and arrived the next day

can't beat the price for this quality product for the pool

This stuff works great! One application and it took care of my low alkilinity.

Works great in my above ground pool.

it works and home delivery is great

Just found out that this product labeled "alkalinity increaser" is actually just baking soda and sold in a 5 pound bag for $10. Sam's club sells 13.5 pound bags of "alkalinity increaser" labeled as baking soda for $8.88. I guess you live and learn.

Even though this item showed in stock at my local store, my order was canceled. Apparently, this is because the item is out of stock at the store. I waited over a month for it to be replenished. I went in person to the store on April 2 and still could not find this item. A relatively unhelpful clerk looked it up and said that they should have 13 on hand. He did not find any on the shelf and told me that he was not authorized to update the quantity to zero because he did not have the authority. This unhelpful clerk told me that I would have to take it up with the store management. I called the stores main number today, press the phone tree options to talk to management, and the phone rang and rang until I was disconnected. The store is undergoing a remodel, and I suspect that the items are lost somewhere. Why does it take an act of Congress to replenish some thing when you could not fulfill an order a month ago?
