Pool water chemistry involves maintaining proper levels of chlorine (1-3ppm based on CYA), pH (7.4-7.6), alkalinity (60-120ppm), and calcium hardness (250-350ppm for plaster). Regular testing with quality kits and proper chemical dosing ensures safe, clear water.
Salt water pools use electrolysis to generate chlorine from dissolved salt, requiring proper water chemistry balance including pH, alkalinity, and CYA levels. They still need regular maintenance and chemical adjustments despite producing their own chlorine.
Weekly pool maintenance involves testing and balancing water chemistry (pH 7.4-7.6, proper chlorine levels), cleaning skimmers and equipment, brushing walls, and vacuuming debris. Consistent weekly care prevents expensive repairs and keeps your pool safe for swimming year-round.
Yes, Walmart does carry pool chemicals both in-store and online, including chlorine tablets, liquid shock, pH adjusters, and algaecides. However, selection varies by location and season, with limited availability of professional-grade products.
Pool alkalinity typically rises due to fresh fill water with high alkalinity, adding pH increasers or certain sanitizers, excessive aeration from water features, and natural processes like algae growth.
Yes, your pool absolutely needs proper calcium hardness levels to prevent equipment damage and maintain water balance. Calcium hardness protects your pool surfaces and equipment from corrosion while preventing scale buildup.
Yes, Costco does carry pool chemicals including chlorine tablets, shock treatments, and pH adjusters, typically at competitive prices. Their products meet the same safety standards as specialty pool stores and can provide significant cost savings for pool maintenance.
