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.
Above ground pool liners typically last 6-10 years, with premium vinyl liners potentially lasting up to 15 years. Proper water chemistry, UV protection, and maintenance significantly extend liner life.
Above ground pool liners typically last 6-10 years, with thicker mil liners lasting longer. Proper water chemistry, UV protection, and careful maintenance can extend liner life significantly.
Above ground pool liners typically last 5-9 years, with overlap liners lasting 5-7 years and beaded liners lasting 6-9 years. Proper water chemistry, UV protection, and regular maintenance can significantly extend liner life.
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.
Pool heater lifespans vary by type: gas heaters last 8-12 years, electric resistance heaters 15-20 years, and heat pumps 10-15 years. Proper maintenance and usage patterns significantly impact longevity.
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.
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.
DE filter grids typically last 1-2 years with proper maintenance, but may need replacement sooner if you notice tearing, permanent staining, or reduced filtration effectiveness.
You should test your water chemistry first, then shock only if chlorine levels are below 1-3 ppm or if you detect any contamination. Fresh fill water typically needs chemical balancing before shocking.
