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 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.
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.
Yes, green pool water can make you sick with infections, gastrointestinal illness, and respiratory problems. The algae indicates dangerous bacteria and parasites are present, making swimming unsafe until properly treated.
Pool algae can cause skin rashes, irritation, and other health issues through direct contact or by creating conditions that harbor harmful bacteria. The key is eliminating algae through proper SLAM treatment and maintaining balanced water chemistry.
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.
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.
Yes, you can shock your pool after adding algaecide, but timing matters. Wait at least 2-4 hours between applications and always add algaecide first, then shock.
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.
No, you should not use pool chlorine tablets in your toilet. Pool tablets contain trichlor which is too concentrated for toilets and can damage plumbing, create toxic gases, and pose serious health risks.
Most pool chemicals take 2-8 hours to fully circulate and settle, depending on the type of chemical and your pump runtime. Always wait before retesting water levels.
