Ascorbic Acid Question

[DKJohnson24]

I am planning on doing an AA treatment to get rid of iron stains, but need to find AA. Is there a non-food grade ascorbic acid? I tried the chemistry store that was linked in the directions on how to do this treatment, but the shipping is more than the AA itself so I was hoping to get it off of Amazon or search it local.

I buy mine off eBay. $27 for 2.2 lbs and free shipping. My pool is about the size of yours and lifting the stains normally takes about 2/3 of the bag. Make sure you get your FC down below 1 before applying and have the pump off for a good 30 minutes so it can freely sink along the edges.
