Earthborn Elements Vitamin C Powder (2 Gallon)

OMG. OMG. OMG. It worked, my pool is like new again. This $ 27 product saved me an unnecessary $8000 cost for pool resurfacing that was advised by a pool care person. For the last 3 years I watched in sadness and despair my pool getting yellow stains that does not scrub off and kept on enlarging slowly until it covered the whole surface, bottom and walls. I spent hundreds and hundreds of dollars buying all kinds of yellow stain treatment and chlorine shocks from Amazon as well as local pinch a penny store who told along with a pool care person who came to see it that my pool is 25 years old and needs to be redone. I saw this ascorbic acid idea on YouTube and decided to try it as a last resort. I ordered a smaller 3.25 lbs size to avoid another waste of money on a large tub. I used about half of it in my 10,000 gallons pool at about 5:00 pm and ran the circulation overnight. I woke up in the next morning and the stains completely disappeared on their own, no scrubbing needed or done. It's a miracle.

Amazing product…..removed stains from pool vinyl and steps almost instantly. Highly recommend.

Great for removing rust from pool

Although this is food grade, I bought it after seeing it used to get rid of the chloromine smell in an otherwise clean hot tub. Although it also brought down the bromine levels, that was easy to correct. The cholromine smell gets so bad that you can't turn the jets on or that smell burns your nose. This is an almost instant fix, with only one teaspoon for our sized hot tub.

I take ~3g of Vitamin C crystals buffered with bicarbonate of soda (baking soda) every morning and every evening. Ratio 4:1, which I THINK follows Pauline's practice (though I can't find the reference now). I take quite a bit more when I think I'm infected with a virus, but that doesn't happen very often. I've never bought a whole gallon (8 pounds) at a time before, but the price was right and the quality seems fine. It might last me close to 2 years, which will take me past the Best Before date, but I've repackaged it in smaller ziploc bags in our cool basement, and I expect it to be good to the last gram. The bucket is a pain to open. Literally. With a pull tab that takes more force to break than my thumb could deliver. Fortunately I reached for my little multitool before I hurt myself and it opened fine. As I was scooping out some of the powder into smaller containers (from previous bulk C purchases), I thought I had hit a big lump, but it was a packet of dessicant! No lumps AFAICS. :-) My only complaint is that the powder is a bit FINER than I like. Not a big deal, but after I spoon out my ~3g with a 1/2t=2.5g measuring spoon, the spoon is covered with fine C powder, like powdered sugar. My favorite bulk C is a bit coarse, and leaves the spoon clean, like ordinary granulated sugar. But that's a small problem, and I'd be happy to buy this again when I finally finish this big batch. :-)

ABSOLUTE MAGIC! We have a liner pool and have been trying to get rid of stubborn stains on the bottom for the past 18 months. Our professional pool company couldn't get rid of them. We scrubbed to no avail. Read up on this product and decided to try it. The stains were gone in FIVE MINUTES! No scrubbing. Drop it in and let the stains vanish. NOTE: This product does take away any chlorine. We simply added shock and the pool went right back into perfect balance. if you don't add the shock you will end up with algae blooms. Our pool looks brand new! The pool is entirely free of stains. Haven't taken the final picture.

Works great cleans pool excellent

Stains disappeared before our eyes!
