Soda Ash vs. Baking Soda??
My pool needs 3 and 1/4 pounds of soda ash, and 4 pounds of alkalinity increaser. Could I just use 3 and 1/4 pounds of baking soda instead of the soda ash, or will it damage my plaster? Baking Soda at the market is quite a bit cheaper than the soda ash at the pool store, and I've heard they're the same thing, but the pool store says that they're not exactly the same. Are they just trying to make a buck?
Thanks to all who help me out with this one!
