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.
Pool filters come in three main types: sand filters (low maintenance, 5-7 year lifespan), cartridge filters (easy cleaning, 1-2 year replacement), and DE filters (finest filtration, requires backwashing every 4-6 weeks).
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.
Pool leaks can occur in the shell, plumbing, or equipment and are detected using bucket tests, dye tests, and pressure testing. Most minor leaks can be DIY repaired, but structural damage requires professional assessment.
To backwash a pool filter, turn off the pump, set the multiport valve to BACKWASH, turn the pump back on for 2-3 minutes until water runs clear, then switch to RINSE for 30 seconds before returning to FILTER mode.
A properly winterized pool can stay closed for 6-8 months safely, while emergency closures should be limited to 2-4 weeks maximum. Beyond these timeframes, water chemistry deterioration and equipment damage risks increase significantly.
Pool filter lifespan depends on the type: cartridge filters last 1-2 years, sand filters last 5-7 years, and DE filters last 8-10 years. Replace when cleaning becomes ineffective or damage occurs.
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.
Yes, you can clean pool filter sand through backwashing, chemical cleaning with muriatic acid or filter cleaners, and eventually replacing it every 2-3 years when cleaning becomes ineffective.
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.
You can shock your pool without running the filter system, but you must ensure proper circulation through brushing and the return jets. The filter doesn't need to be running, but water movement is essential for even chemical distribution.
Pool filters work by pumping water through filter media that traps debris, dirt, and contaminants. The three main types are sand filters (use sand to trap particles), cartridge filters (use pleated fabric), and DE filters (use diatomaceous earth powder).
Variable speed pool pumps use permanent magnet motors and electronic controls to adjust RPM from 600-3450, providing precise flow control and significant energy savings compared to single-speed pumps.
Your pool pump isn't working properly if you notice weak water flow, unusual noises, air bubbles in return lines, high pressure readings, or the pump running but not circulating water.
Pool cartridge filters typically last 1-4 weeks between cleanings and should be completely replaced every 3-6 months depending on usage, bather load, and maintenance frequency.
