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.
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.
Running a pool pump without a filter will damage your pump's impeller, allow debris to circulate, and create dangerous pressure imbalances. Only run briefly in emergencies while replacing the filter cartridge or cleaning DE/sand media.
Used pool filter sand can be used in gardens after thorough cleaning and testing, but it may contain chlorine residue and accumulated contaminants that could affect plant growth.
Pool filter sand should not be used in aquariums as it contains sharp edges, chemical treatments, and lacks the proper grain size for fish safety. Use aquarium-specific sand instead.
Yes, you can vacuum a pool on recirculate, but it won't filter debris - it only circulates water back to the pool. This setting is useful for extremely dirty pools to avoid clogging your filter system.
Yes, Walmart does carry pool filter sand both in-store and online, typically available from spring through summer. They stock brands like HTH and Quikrete, with 50-pound bags ranging from $8-15.
Sand is not always required under above ground pools, but it provides excellent leveling and protection. Pool pads, foam boards, or crushed stone can also work depending on your ground conditions.
You need a new pool filter if it's damaged, cleaning doesn't restore flow, or it's reached its replacement schedule (1-2 years for cartridge, 5-7 years for DE grids, 10-15 years for sand). Check for tears, reduced flow, and cleaning frequency to determine replacement needs.
Yes, you can clean pool filters with diluted household bleach (1 part bleach to 10 parts water), but avoid bleach on DE filters and always rinse thoroughly afterward to prevent equipment damage.
You can paint certain types of pool liners, but only fiberglass and concrete liners should be painted. Vinyl liners cannot be successfully painted and painting them will void warranties and cause peeling.
While you can technically leave your pool covered all summer, it's not recommended as it creates anaerobic conditions that promote algae growth and equipment damage. If you must keep it covered, you'll need modified maintenance procedures.
Above ground pools typically last 7-15 years, with steel frame pools lasting longest (10-15 years) and inflatable pools shortest (2-5 years). Proper maintenance, water chemistry, and winterization can significantly extend their lifespan.
Yes, you absolutely need a pool liner pad for your above ground pool. It protects the liner from punctures, provides cushioning, and extends the liner's lifespan significantly.
