Phosphate Problems

Phosphates are nutrients (forms of phosphorus) that serve as the primary food source for algae. They enter pools through fertilizer runoff, leaves and organic debris, source water, some pool chemicals, and detergents. Phosphates are measured in parts per billion (ppb) and don't directly affect water clarity or safety, but levels above 100 ppb promote algae growth even with proper chlorine levels.

Phosphates don't directly cause algae, but they feed it. Think of phosphates as fertilizer for algae - without this food source, algae struggles to grow even if spores are present. Pools with phosphates above 500 ppb experience frequent algae blooms despite maintaining proper chlorine levels. Removing phosphates starves algae and makes chlorine more effective at prevention.

Remove phosphates using commercial phosphate removers containing lanthanum chloride. Calculate dosage based on pool size and current phosphate level (typically 1 quart per 10,000 gallons removes 300-500 ppb). Add remover slowly around pool perimeter, run pump 24-48 hours continuously, expect temporary cloudiness, and clean filter when pressure rises. Re-test after 48 hours and repeat if necessary.

Phosphate levels: 0-100 ppb is ideal for algae prevention, 100-500 ppb requires monitoring and preventive measures, 500-1000 ppb significantly increases algae risk and needs treatment, above 1000 ppb virtually guarantees algae problems and requires immediate removal. Most pool professionals recommend keeping phosphates below 100 ppb for easy maintenance.

Primary phosphate sources include: lawn fertilizer runoff (biggest contributor in residential pools), decomposing leaves and organic matter, fill water (many municipalities add phosphates), some metal sequestrants and stain preventers, body care products and detergents, bird droppings, and dust/dirt containing phosphorus. In Southlake, Westlake, Grapevine area, both fertilizer runoff and municipal water are major sources.

Phosphate removal isn't always necessary - it depends on your levels and algae history. If phosphates are below 100 ppb and you have no algae issues, removal isn't needed. However, if you experience recurring algae, high chlorine demand, or phosphates above 500 ppb, removal will make pool maintenance much easier and reduce chemical costs long-term.

Phosphates return because their sources aren't eliminated. Common reasons: continued fertilizer runoff from landscaping, fill water contains phosphates (test your tap water), ongoing leaf and debris accumulation, using phosphate-containing chemicals, poor drainage directing runoff into pool. Address the source to prevent costly repeated treatments.

Phosphates themselves are not harmful to swimmers - they're naturally occurring nutrients. However, high phosphates promote algae growth, which can harbor bacteria, reduce water clarity creating safety hazards, increase chemical demand affecting water balance, and create slippery surfaces. The algae enabled by phosphates poses the real risk, not the phosphates themselves.

The most effective phosphate removers use lanthanum chloride (rare earth element) technology. Popular brands include PhosFree, PHOSfloc, and SeaKlear. These bind phosphates into particles your filter removes. Natural or enzyme products don't actually remove phosphates. Choose based on your phosphate level - higher levels need stronger commercial products.

DIY phosphate removal costs $100-250 for test kit ($20-40) and remover ($30-50 per quart, may need multiple). Professional service by CoOpPools runs $150-350 including testing, proper treatment, filter cleaning, and prevention plan. Since our worker-owned technicians aren't on commission, they'll honestly assess if treatment is necessary and recommend the most cost-effective approach.
