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.
The SLAM method (Shock Level And Maintain) clears green pools by maintaining high chlorine levels continuously until water clears. Use liquid chlorine to reach shock level based on CYA, maintain 24/7 until overnight chlorine loss is 1ppm or less.
Most pools don't need algaecide if you maintain proper chlorine levels (1-3ppm FC) and adequate CYA (30-50ppm). Algaecide is mainly useful for prevention during high-risk periods or as backup insurance, not for treating active algae blooms.
Yes, saltwater pools absolutely need cyanuric acid (stabilizer) to protect the chlorine generated by the salt cell from UV degradation. Maintain CYA levels between 70-80 ppm for optimal protection.
Clear cloudy pool water by testing and balancing chemicals first, then shock with liquid chlorine to 2-3x your stabilizer level, run the filter 24/7, and backwash frequently until water clears completely.
Most pools don't need phosphate remover if you maintain proper chlorine levels. Only consider phosphate removal if you have persistent algae problems despite balanced water chemistry and proper sanitizer levels.
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.
Pool salt cells use electrolysis to convert dissolved salt (sodium chloride) into chlorine gas and sodium hydroxide. The chlorine sanitizes your pool while the sodium hydroxide raises pH, creating a continuous chlorination cycle.
Yes, you can shock your pool two days in a row if your chlorine levels haven't reached the proper shock level or if you're treating algae. However, test your water first to avoid over-chlorination.
You can shock a pool with high pH, but it reduces chlorine effectiveness significantly. Lower pH to 7.2-7.4 first for optimal shock treatment, or use 25-50% more chlorine if shocking immediately is necessary.
Yes, you can shock your pool after adding alkalinity, but wait 4-6 hours first and test your water to ensure pH is below 7.6 for maximum chlorine effectiveness.
Salt water pools still require chemicals for proper water balance, including pH adjusters, stabilizer, and calcium hardness increasers. The salt chlorine generator only produces chlorine, not other essential chemicals needed for safe swimming water.
Clear cloudy pool water by testing and balancing your chemistry first, then shock with liquid chlorine to 3x your CYA level and run your filter 24/7 until the water clears completely.
You don't necessarily need to shock your pool weekly. Shocking frequency depends on usage, weather conditions, and your free chlorine levels. Most well-maintained pools need shocking every 2-3 weeks or when combined chlorine exceeds 0.5 ppm.
Above ground pools require proper installation on level ground, regular liner maintenance (lasting 6-10 years), and balanced water chemistry with chlorine levels based on CYA. This comprehensive guide covers everything from DIY installation to winterization and troubleshooting common issues.
