soda ash bought at the co op? CHEAP CHEAP CHEAP

i buy soda ash from my local CO-OP. i use it in my pool, its 22 bucks for a 50 lb bag. Research shows no difference in the soda ash bought from a fish store vers a co-op. thoughts? Furthermore i have consulted two agricultural engineers my (wife and father)on the matter and they called me a sucker if i bought that stuff from a fish store, cause soda ash is soda ash.

Baked plain jane arm and hammer baking soda in the oven at 350 for about an hour will also give you soda ash. And it's probably cheaper still.

Google Randy's recipe.

Walmart sells the big 12 pound bags for about 8 bucks. not cheaper, but I feel better using food grade baking soda.

I work for a company that makes soda ash. There are some differences in grades but you are looking at that last .5% as it is 99.5% pure. There are some differences in metal and organics content that can make a difference in some chemical processes but I'd be OK using tech grade soda ash.

No way cooking baking soda would be cheaper. You make baking soda from soda ash. Also when you bake it you lose 28% of the weight.

A lot of soda ash products seem to be fine. The impurities could be an issue, at least in theory, but people are successful with a wide range of products. Most of the baking soda in the US is produced from a form of sodium carbonate that is mined and purified. The sodium carbonate is then processed into baking soda.
