Phosphate is a vital plant nutrient and the presence in swimming pool water, even at low concentrations, can cause accelerated algae growth in poorly maintained pools. Pools, that are properly maintained, usually do not have unexpected difficulty controlling algae, even in the presence of phosphates.
Low pH levels in a pool can be caused by rainwater and other foreign particles getting into pool and changing the chemical make-up of the water. Corrosion of metal accessories, burning of the nose and eyes, rapid chlorine reduction and itchy, dry skin and scalp can be signs of low pH levels in a pool. Low pH levels also reduce the sanitation of a pool. Regular testing and chemical treatment can help to maintain pH levels. Utilize these tips to raise pH in a pool.
