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.
Wait 24-48 hours after shocking your pool before adding algaecide, allowing chlorine levels to drop below 5 ppm. Test your water first to ensure proper chemical balance and maximum algaecide effectiveness.
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.
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.
To raise pool pH, add sodium carbonate (soda ash) for quick increases or sodium bicarbonate (baking soda) for gradual increases. Test first, calculate dosage based on pool size, and add chemicals slowly with circulation running.
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.
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.
You can shock your pool during the day, but it's less effective due to UV rays breaking down chlorine. Evening shocking after sunset provides better results and longer-lasting sanitization.
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.
To raise pool stabilizer levels, add cyanuric acid at 1.3 pounds per 10,000 gallons to increase CYA by 10 ppm. Use granular stabilizer in a sock method or liquid stabilizer for faster results.
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.
Wait 8-24 hours after shocking before vacuuming your pool, depending on chlorine levels and shock type. Test free chlorine first - it should drop below 5ppm for safe vacuuming.
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.
