It is a "pool product", and I won't be buying it (if I see it in the store) unless I can determine what the ingredients are. I sent them a "contact us" note, asking what the active ingredients are. If Arm and Hammer has made a tab of baking soda, without anything else, they should have named it something like "baking soda pool tabs" instead of the confusing and vague "Clear Balance". They also, regardless, should have some ingredient list via their website. They already have a lock on my loyalty with the baking soda, in my house and my pool. I don't think there would be an issue if that is all it contains, could be a useful product. I would find it weird if it has a lot of anything else in it, since most of the information they give on their boxes and website supports BBB. Not sure I'd want to add more stabilizer when I use the tabs in the summer (after I clean and balance the pool myself, use them just to keep a minimum level of chlorine). I have less than 30ppm in there right now, need to vacuum the last of the debris out to waste, so I will wait to add CYA (so keeping chlorine levels up is a pain right now). I can not explain why, might be just good fortune, but I have never had more than 70-80 ppm in the last three years, even though I use tabs part-time.

Anyway, I'm curious about this product, maybe someone at Arm and Hammer will get back to me next week with an answer, will be glad to share.
