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 winterization involves balancing chemicals, protecting equipment, and proper closing procedures. The process varies by climate zone but typically includes shocking, lowering water levels, and winterizing plumbing to prevent freeze damage.
Yes, most pool owners need pH Up and pH Down chemicals to maintain the ideal pH range of 7.4-7.6, but you may not need both products depending on your water's natural tendencies.
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.
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.
Pool chemical shelf life varies dramatically: liquid chlorine lasts 2-5 years, granular chlorine 2-3 years, while pH adjusters and alkalinity increasers can last indefinitely when stored properly.
Yes, saltwater pools absolutely need cyanuric acid (stabilizer) to protect the chlorine generated by the salt cell from UV degradation. Maintain CYA levels between 70-80 ppm for optimal protection.
Yes, you can shock your pool after adding alkalinity, but wait 4-6 hours first and test your water to ensure pH is below 7.6 for maximum chlorine effectiveness.
Yes, you should cover your pool heater in winter if it's not being used, especially for heat pumps and electric heaters. Gas heaters typically need less protection but benefit from covers in harsh climates.
Yes, you need a building permit for swimming pools in the Philippines, regardless of size or type. The process involves submitting plans to your local government unit (LGU), paying fees, and obtaining approval before construction begins.
Most states don't require a license for basic pool cleaning services, but commercial pool service businesses may need business licenses or permits. Chemical handling and pool maintenance involving equipment repairs often have additional requirements.
Yes, you absolutely need to winterize your pool heater if temperatures drop below 40°F in your area. Failing to properly winterize can cause expensive freeze damage to internal components and plumbing lines.
Salt water pool systems use electrolysis to convert dissolved salt into chlorine sanitizer. The salt cell generates chlorine from sodium chloride, eliminating the need to manually add chlorine while maintaining proper sanitation.
