Pool chlorine can clean concrete when properly diluted (1:10 ratio), but muriatic acid or specialized concrete cleaners are safer and more effective options for most concrete cleaning tasks.
Pool pH down can technically lower plant soil pH, but it's not recommended due to high chemical concentrations and lack of nutrients. Use garden-specific pH adjusters instead for plant safety.
Pool water can be used for garden irrigation, but chlorine levels must be below 0.1 ppm and salt levels under 1,000 ppm. Dechlorinate first and avoid watering sensitive plants directly.
Your pool needs phosphate remover when levels exceed 500 ppb and you're experiencing persistent algae growth despite proper chlorine levels. Test phosphate levels with a reliable test kit to determine if removal is necessary.
