## Description

desertcart.com : In The Swim Pool Shock – 68% Cal-Hypo Granular Sanitizer for Crystal Clear Water – Defends Against Bacteria, Algae, and Microorganisms - 50 Pounds : Patio, Lawn & Garden

Review: Fantastic Product - The package was originally mailed on time, but tracking showed that there was a problem with shipping, and it was rerouted back to the seller. I had to reach out several times. They responded saying that another order would be sent, but I never received a new tracking or order number, even though I had paid for it and needed it weeks ago. It finally arrived. I love this stuff and have ordered from the same seller in the past without any trouble. That is why they still got 5 stars. It goes a long way since it is a strong concentrate meant to be diluted. I use it around the house and farm, and occasionally to treat my camping and hiking gear.
