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.
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).
To fix low stabilizer, add cyanuric acid at 1 pound per 10,000 gallons to raise CYA by 10ppm. For high levels over 80ppm, partially drain and refill your pool, as there's no chemical way to lower stabilizer.
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.
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.
Whether you need to winterize your pool depends on your climate zone. Areas with freezing temperatures require full winterization, while warmer regions need only reduced maintenance and chemical adjustments.
Yes, salt water pools do freeze, but at slightly lower temperatures than fresh water (around 28-32°F vs 32°F). The salt content provides minimal freeze protection, so proper winterization is still essential.
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.
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.
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.
Most modern pool vacuums, especially robotic and suction-side cleaners, can safely run all night. However, proper setup and equipment condition are crucial for safe overnight operation.
Above ground pools typically range from 48 to 54 inches deep, with 52 inches being the most popular choice. The depth you choose depends on your family's swimming needs and safety requirements.
