This is equivalent to a spa product and much more economical. It works just as well.

5.0 out of 5 stars My new pool ritual…
Reviewed in the United States on January 5, 2023
So I’ve used the product twice now. I honestly wish I had taken before and after pictures but I’ll share my experience anyways.

Towards the end of Summer I noticed algae starting to appear on the shaded side of the pool. I tried boosting the chlorine, shocking the water, and algae fighting products and nothing worked. In combination with the chlorine tabs I also staggered it with clarifying tablets like I use throughout the Summer to keep the water balanced, but again nothing helped.

A family member mentioned using alkalinity plus. They recommended 25lbs but since other products failed I just bought two to try it. By this time my pool was green. I emptied both 5lbs bags as soon as they arrived and ran the filter for 24 hours. 24 hours later the pool was crystal clear! I brushed the walls to clear any remaining algae and saved our Summer!

One more if you’re still following along. I have a pet peeve about keeping the pool clean during the Fall and Winter as well. Once the leaves started falling here in Texas the water started turning green again. I purchased 25lbs knowing that this stuff really works and boom, water has been crystal clear and no algae has appeared.

I absolutely will add this to my pool rituals along with my balancer tablets and chlorine. This is an amazing, Summer extending, making dad look like a hero product.

If you have algae growth, green water, or just have a pet peeve about keeping that water sparkling then this product should be included with your regular pool maintenance moving forward.

It took the whole bag but it helped to clear our above ground pool.

I bought this to use in my hot tub. All of the levels were off and this fixed most of them. I had to call a local spa store to figure out how much to use.

5.0 out of 5 stars Great value compared to hot tub chemical packaging/price
Reviewed in the United States on October 20, 2023
Fraction of the cost of the same material sold for hot tubs; you just have a little less guidance on how much to use; so just take it slowly in small amounts and test in between.
