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.
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.
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.
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.
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.
Clear cloudy pool water by first testing chemistry levels, then shocking to proper FC/CYA ratio, running filtration 24/7, and using clarifier if needed. Most cases resolve within 24-48 hours with proper chlorine levels.
To lower pool chlorine levels, stop adding chlorine and let it naturally dissipate over 24-48 hours, or speed up the process using UV exposure, adding fresh water, or using sodium thiosulfate neutralizer.
Pool chlorine can make you sick when levels are too high (causing irritation) or too low (allowing harmful bacteria). Proper chlorine levels of 1-4 ppm based on your CYA level prevent illness.
Pool algae forms when microscopic spores enter your water and find ideal conditions: sunlight, nutrients (like phosphates), warm temperatures, and unbalanced water chemistry with insufficient chlorine levels.
Salt water pools do contain chlorine - the salt chlorine generator converts salt into chlorine through electrolysis. You still need to maintain proper chlorine levels and test regularly.
Yes, you may need to shock your pool in winter, but less frequently than summer. Winter shocking depends on your pool type (open vs closed), water temperature, and current chlorine levels.
Pool algaecides work by disrupting algae cell walls and metabolic processes to kill and prevent algae growth. However, proper chlorine levels are more effective for treating existing algae problems than algaecides alone.
Pool covers don't directly cause algae, but they create ideal conditions for growth by blocking UV rays that normally help chlorine kill algae. Maintain proper chlorine levels and consider removing covers periodically to prevent issues.
You should wait until chlorine levels drop below 5 ppm before covering your pool after shocking. Covering too early can trap high chlorine concentrations and damage your pool cover.
