Citric acid treatment for pools.

This is a good treatment if your pool has a lot of staining and the spot cleaning is not an option. Depending on the pool size and stain size another method besides treating the whole pool with citric acid is to treat the stain directly that is fill a literal sock with citric acid and put it directly on the stain initially with circulation off. Deactivate excess metals with a metal reducer like metal free or metal klear add a 1 2 pound of ascorbic acid per 10 000 gallons or water. The polyquat the citric acid and the metal sequestrant tend to cause high chlorine demands so you may have to supplement the swcg with bleach to get the chlorine to register at first.

I cover using bulk ascorbic acid and also using natural chemistry stain free which is citric acid. This is how you use a large amount of ascorbic acid to treat staining in your entire pool. Treat large stains by adding ascorbic acid to the pool water by sprinkling it evenly over the surface of the water. Citric acid is a gentler stain remover than muriatic acid another form of acid used to remove stains and resurface swimming pool interiors.

You might be able to filter it out over time but as long as you have both citric acid and calcium in the water more precipitates will form. It does not harm a pool to have such a thin layer removed it simply clears away the stain. Start by using a 1 2 pound of ascorbic acid per 10 000 gallons of water in the pool. After 12 hours brush and circulate.

Your best bet might be to empty the pool clean it out and start over. Run your filter for at least 1 hour. My pool has some staining on the steps and some of the walls. Citric acid removes the stained area of a pool when applied by eating away the top layer of the pool s surface.
