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.
Used pool filter sand can be used in gardens after thorough cleaning and testing, but it may contain chlorine residue and accumulated contaminants that could affect plant growth.
Yes, you can vacuum a pool on recirculate, but it won't filter debris - it only circulates water back to the pool. This setting is useful for extremely dirty pools to avoid clogging your filter system.
Pool stabilizer (cyanuric acid) dissolves slowly and requires warm water, agitation, and patience. The most effective methods are pre-dissolving in a bucket with hot water or using the sock method directly in your pool.
While pool pH down and hydroponic pH down both lower pH, pool chemicals often contain additives that can harm plants. Use pH adjusters specifically designed for hydroponics to ensure plant safety and optimal nutrient uptake.
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.
Yes, you absolutely need pool chemicals even with a sand filter. Sand filters only remove physical debris and particles - they cannot sanitize water or balance pH, alkalinity, and other chemical levels required for safe swimming.
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.
