I saw in a mailed pool store catalog a gallon on Natural Chemistry brand Liquid Stabilizer. They compare it with the granular CYA, but it is "not an acid, it's a salt" and "has a pool friendly pH of 8.0". Those are quotes from the catalog. I searched for a MSDS it, but couldn't locate one. They do not list the ingredients of the product.
I'm just curious if it would be worth the 24 bucks. I have a really difficult time using my granular CYA, It seems like that stuff never wants to dissolve, even after a week. I've even used a drywall mud mixer with about 4gallons of water trying to dissolve that stuff.
