Earthborn ElementsVitamin C Powder (2 Gallon)

This works great! I used it for my pool to get rid of yellow spots .

My white pool steps will turn a golden rust color when the pH and chlorine gets out of normal limits. I just sprinkle some of this vit. c powder on them, and they immediately turn back white. If your whole pool is stained just pour some in and it will remove the stain in about an hour. It will however deplete all of the chlorine from your pool.

This is awesome and so much more affordable than the pool store versions. Once you put it in, I recirculate the water and in a day, the whole pool is stain free and looming awesome. Initially, it is magic where you put it in, but give it time , then the rest of the pool looks just as clear. Highly recommend it for metal stains!

Vitamin C Arrived on time....and after removing the two gallon bucket from it's box....I was very excited to start cleaning the HEAVY and dark well water rust stains from my large inground vinyl lined pool. I started on a part of the pool that is supposed to be solid....a 4'x6' bright white plastic lounging area near the skimmer....it was terribly, terribly stained....I put about three of four cups of the V-C power into a small tight-thread burlap bag (a sock would absolutely also works)....it literally wiped the rust away like spilled milk on a countertop.....AND it's also fun and HEALTHY to wet your index finger...stick into the bucket and savor that vitamin C deliciousness. I want to scream how much I love this product from a mountain top...and hey, I live on the top of a mountain...so there's that! :) DO NOT PAY POOL COMPANYS for Ascorbic Acid....they'll charge you 5-10 time more for their "for the pool' packaged Vitamin C.

This is good to treat very light stains.

This is a great course of vitamin c. I’ve used plenty of vitamin c supplements and for the cost, this one is well worth it.It does take a minute to dissolves but if you stir well it’s not a problem. I take it daily and feel well and healthier since I’ve incorporated it into my routine. I will continue to purchase this product as I go through it. Would definitely recommend!

I can't guarantee the taste or if it's easy to swallow but my pool has never complained. I use a cup at the beginning of each month (12 x 28 ft pool in ground) and have no problem with any yellow issues (due to metal) on the bottom of my pool. It took years for me to find something to take the yellow out and this works great. It's not going to work on algae, only metal staining which we didn't even know was the problem.I had tried Vit C once before and it didn't work. When I was cleaning out the utility room I saw I had some in a jar and threw it in the pool rather than the trash. My husband asked what I had done to the pool and low and behold, the yellow was gone! It was amazing and looks so good now. Now it's part of my monthly regiment for our pool.

I bought a house and the pool was stained all over. I called some pool installers and they gave me a quote to resurface it. $25,000!! A friend told me about Vitamin C. I had nothing to lose. I dumped the right amount in for the size of my pool and ran it overnight. The next morning my pool looked brand new. The only thing I had to do was replace the paper filter elements. Easy.
