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.
You can vacuum your pool after adding most chemicals, but timing matters. Wait 15-30 minutes for liquid chemicals to circulate, and 2-4 hours for granular chemicals to fully dissolve before vacuuming.
Most pool owners do need a pool vacuum for thorough cleaning, but the type depends on your pool size, debris load, and maintenance preferences. Manual vacuums work for small pools with light debris, while automatic cleaners are essential for larger pools or heavy leaf loads.
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.
Salt water pools are not self-cleaning and require regular maintenance including proper water chemistry balance, algae prevention, and equipment upkeep. The salt water generator only produces chlorine automatically but doesn't eliminate the need for active pool care.
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.
Pool skimmers work very effectively when properly maintained, removing 80-90% of surface debris before it sinks. However, their effectiveness depends on proper water level, basket maintenance, and adequate pump flow.
Yes, pools can leak through tile grout when it becomes cracked, deteriorated, or improperly sealed. Grout leaks typically occur at the waterline where freeze-thaw cycles and chemical exposure weaken the grout over time.
Yes, you absolutely need to wash pool filter sand before installation. New sand contains dust, debris, and fine particles that will cloud your pool water if not properly cleaned first.
Cartridge pool filters cannot be backwashed like sand or DE filters. Instead, they must be removed and cleaned by hosing off debris, soaking in cleaning solution, and rotating between multiple cartridges for best results.
Yes, Costco does carry pool vacuums both in-store and online, primarily during pool season (March-August). They typically stock robotic cleaners from brands like Dolphin and Polaris, plus manual vacuum heads and hoses.
Pool jets can indeed leak from loose fittings, cracked housings, or plumbing connections behind the wall. Most jet leaks occur at the fitting where the jet screws into the return line or from deteriorated gaskets and O-rings.
