what does muriatic acid do for a pool

Muriatic acid plays a multifaceted role in pool maintenance, primarily in pH adjustment and water balance. The main reason that muriatic acid needs to be added into pool water is because it can help reduce pH levels that have become too high. High pH levels are known to lead to the development of scale. Along with balancing the pH levels of your pool water, muriatic acid is strong enough to kill mold, remove rust stains, get rid of calcium deposits, and clean the surfaces of your pool. Muriatic acid is also useful for lowering high alkalinity and pH levels in your water, cleaning cartridge filters or D.E. grids, and removing pool surface stains. It is much more affordable when compared to sulfuric acid and hydrochloric acid, which is why it’s recommended that you use it for your pool cleaning needs. Muriatic acid is also a powerful stain remover. It can remove rust stains off of your pool’s surfaces, resurface your concrete pool deck, and clean. However, it is important to note that muriatic acid is highly corrosive, which means that you need to be very careful whenever you use it. If you want to add muriatic acid to your pool, it is recommended that you follow the proper safety precautions and know exactly how to use it before you add it to your pool water.
