Duda Energy sc1f Pure Sodium Carbonate Dense Soda Ash Na2CO3 pH Adjust Chemical Spa Pool Cleaning Dishwasher, 1 lb.

I used it to make a clothing stain removing liquid.

I enjoy shopping with Amazon, Quality and just what you need at a fair price

Works great for producing precipitate of ORMUS!

I recently bought this to add my homemade laundry detergent and stain remover. Though this is the first sodium carbonate product I have used, it works well and I will buy again.

Reason for 1 star it mixed up cloudy. I was going to use as a alkalinity adjuster for reef tank. Not clear = not pure. So I dumped down the drain used rodi water with a tds of 0 to mix with. Don’t believe purity ratings are accurate.
