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).
Pool opening involves removing winter covers, inspecting equipment, reconnecting plumbing, and balancing water chemistry. Start with equipment inspection, fill and reconnect systems, then shock and balance chemicals before swimming.
Pool heaters can fail due to electrical issues, gas problems, water flow restrictions, or component failures. Most common issues like pilot light problems, low water flow, and thermostat malfunctions can be diagnosed and often fixed without professional help.
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.
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.
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.
Yes, you can run your pool pump with a solar cover on. The pump will still circulate water effectively underneath the cover, and this is actually recommended for maintaining water quality.
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.
Yes, diatomaceous earth (DE) pool filters require regular backwashing, typically every 4-6 weeks or when the pressure gauge reads 8-10 PSI above the clean starting pressure. After backwashing, you must add fresh DE powder to recharge the filter.
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 DE filter grids typically last 1-3 years with proper maintenance, while DE powder needs replacement every 2-4 weeks. Signs of worn grids include shortened cleaning cycles and decreased water clarity.
No, you cannot backwash a cartridge filter. Unlike sand or DE filters, cartridge filters must be physically removed from the housing and cleaned manually with water or filter cleaner.
Yes, you need to run your pool pump in winter, but for shorter periods - typically 4-6 hours daily in mild climates or continuously during freezing weather to prevent equipment damage.
Running a pool pump without a filter will damage your pump's impeller, allow debris to circulate, and create dangerous pressure imbalances. Only run briefly in emergencies while replacing the filter cartridge or cleaning DE/sand media.
