Citric Acid For Pool Water

Citric acid for pool water.

Place the parts in the container and cover them with warm water. Use a half a pound of vitamin c for every 10 000 gallons of water. I cover using bulk ascorbic acid and also using natural chemistry stain free which is citric acid. High levels of cyanuric acid cya in pool water can cause issues.

Cyanuric acid is a precursor to those meaning what you put in your pool is not the same substance you use to kill dandelions in your driveway. A no drain acid wash is a term coined for a pool plaster cleaning or descaling process without draining the pool water. Add the citric acid powder and stir it in. That s just a fancy way of saying it protects your pool s chlorine from the effects of sunlight.

Citric acid is a gentler stain remover than muriatic acid another form of acid used to remove stains and resurface swimming pool interiors. Cyanuric acid is used in swimming pools to lower the rate of photochemical reduction of chlorine hypochlorous acid and hypochlorite ion. Citric acid removes the stained area of a pool when applied by eating away the top layer of the pool s surface. This is a good treatment if your pool has a lot of staining and the spot cleaning is not an option.

It s sold in liquid or granule form. This way you only need to cover them with a shallow pool of water. For my vinyl pool students in the class please read chapter 7 stains in a vinyl liner pool. It does not harm a pool to have such a thin layer removed it simply clears away the stain.

When you get the ascorbic acid in the water you can turn on the pool pump and let the filters circulate the water for about a half hour. This is how you use a large amount of ascorbic acid to treat staining in your entire pool. Essentially the ph of the pool water is reduced to a very acidic level of around 1 0 and an alkalinity level close to zero. If you are treating larger stains or decided to buy a liquid acid sprinkle the acid evenly around the pool.

Cyanuric acid is sometimes abbreviated as cya and it s also called pool conditioner or pool stabilizer. I used probably a 1 2 ounce of citric acid with 15 ounces of water.
