I am about to deal with the dread of annual metal stain removing from the walls of my light blue fiberglass pool. I am looking for advice on where to get pure ascorbic acid.
3 years ago I bought 3lbs on Amazon (PC NetwoRx Pure Ascorbic Acid (Vitamin C) Powder). I ended up dumping all 3 lbs and it barely made a difference after 24 hours. I went to my local pool store and bought their Super Stain Gone which is $50/lb and the I gently sprinkled it around the pool, gently, right up against the wall. It worked like a charm, stains gone in 10 seconds as I moved around and then I followed the regular process. And I did the same last year. But 4x$50 is really expensive. I have no doubt that it was the product itself. But the guys at the store told me it's glorified ascorbic acide unlike their much cheaper Stain Gone (no Super) product which is citric acid. And yes, a single pill of vitamin C cleans the spot.
So I know I can remove the staining for $200 + all the other stuff that's part of the process. Is there any cleaner/purer AA that would get the job done for less $? Thank you so much!
