Amazon.com : In The Swim Instant Liquid Chlorine for Swimming Pools - 4 x 1.07 Pound Bottles : Patio, Lawn Garden
That is the link to the product in Amazon. It says it is chlorine granules.. 4/ 1lb bottles. Looks like it is condensed.
Anyone tried this? I'm so tired of buying gallons and gallons of liquid chlorine.. feeling like I'm not being very environmentally sound.
