    Question about Calcium Chloride

    Calcium Chloride is sometimes used in concrete and can be purchased from Lowes or Home Depot. Is there any reason it cannot be used in pools? It's a whole lot cheaper than the pool store stuff.

    Not sure, but one of the alternatives we mention are certain ice melters.

    Re: Question about Calcium Chloride

    Calcium chloride is just fine, essentially the same as what the pool stores sell. From what we have seen, it is only available in colder climates, as it is primarily used as an ice melter or to help concrete set properly in cold weather.

    It's also sold as a product called Damp Rid. Used as a moisture absorber in basements and humid areas. It's more expensive than ice melt, but it will melt ice in a pinch. It's 99% calcium chloride.

    You just want to make sure to use a product that doesn't have metal contaminants such as iron.

    Re: Question about Calcium Chloride

    Iron contamination is my main concern, but none of the products I've seen list minor contaminants. I suspect (but not sure) that the calcium chloride sold in pool stores is the same as sold by Lowes or Home Depot. But I would hate to be wrong and end up with iron in the pool so I was wondering if anyone had any experience.

    Re: Question about Calcium Chloride

    You can get it even cheaper at concrete plants. Typically called. Dow Flake. Its roughly 50% the cost than if purchased at lowes or home depot

    Re: Question about Calcium Chloride

    Both DowFlake and Peladow are good choices.

    Re: Question about Calcium Chloride

    Just a follow up - the pool store sells a 25 lb bag of Dow Flake for $14.95. Lowes sells the identical 25 LB bag for $6.95.
