Earthborn ElementsVitamin C Powder (1 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.

Used it on my pool! Its amazing!!! removed all the stains and left the pool clear as glass!

Why did you pick this product vs others?:I was struggling with a organic stain in my pool. I didn't open my pool last year and when I opened it this year it had lots of leaves in it. Their was some holes on my cover. I have tried different products that you get at a pool store. None worked for the walls of the pool. I have spent hundreds of dollars trying to get the stains removed. I came across this product and I was blown away!! It took all the stains out like an magic eraser!! I put some powder in a skimmer sock and rubbed the vinyl wall and as soon as the vitamin C touched the vinyl it instantly came out!!!! You will not be disappointed!

Vitamin C powder aka ascorbic acid is the only chemical that removes the stains on my fiberglass pool. And it is way cheaper than buying it at the pool store.

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. :-)

I was skeptical and had tried several things that took lowering pH to no avail. I just dumped this into my pool and 24 hours later, it looked brand new. The corners and the areas in front of the jets were stained orange. There most have been a fine layer all over the pool because the whole thing is bright and brand new now. I’m beside myself with happiness. I did not want to buy a new liner but I hated the stains.

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.

Great product. It works just as advertised.
