I did a search on here. I'm on the BBB method but have at least 10lbs of smart shock left. Does it add CYA? I couldn't find any info on it. Since my CYA is out the roof I don't need to add more. Thanks


Yes, it is dichlor (with some copper in it too! :shock: ) so for every 1 ppm FC you add with it you are adding .9 ppm CYA, essentially it is half CYA! I would not advise using it for shocking.
