How to find the right Pool Filters & Media AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Pool Filters & Media

Filter type match: Media must match the filter type: silica sand or glass media for sand filters, DE powder for DE grids, and pleated cartridges for cartridge filters. Never add DE to a cartridge-only filter unless the manufacturer allows it. Wrong media clogs or passes through the internals and can damage laterals or grids.
Sizing to pump and pool: The filter's rated flow must meet or exceed the pump's flow. Size it so the full pool volume turns over in roughly 8 hours. An undersized filter runs at high pressure, needs constant cleaning and lets water go cloudy.
Sand grade: Use #20 pool-grade silica, about 0.45–0.55 mm. Fill to the depth on the tank label, never with play or construction sand. Grain size sets both filtration fineness and backwash behavior. Off-spec sand channels or ends up in the pool.
Glass media quantity: Glass media replaces sand at a lower weight than the sand rating. Follow the media maker's conversion for your tank size. Filling to the sand weight overfills the tank and leaves too little freeboard for backwashing.
DE dose: Dose DE to the filter's square footage, as printed on the tank label, after every backwash or cleaning. Too little DE leaves the grids exposed and fouls them. Too much bridges the grids and spikes pressure.
Cleaning trigger: Backwash or clean when pressure rises about 8–10 psi above the clean-filter baseline. Cleaning on a schedule rather than on pressure wastes water or strains the pump.

Hayward: Broad sand, cartridge and DE filter range with widely stocked parts.
Pentair: Major filter maker (Clean & Clear, Triton, FNS lines) with long parts support.
Jandy: Zodiac's equipment brand for cartridge and DE filters.
Intex: Above-ground pump and filter combos that use proprietary cartridge types.
Pleatco: Large aftermarket cartridge maker with cross-reference charts.
Vitoria / ZeoSand: Alternative sand-filter media such as glass and zeolite.

Mixing filter types' media, for example DE in a sand filter without a DE-capable design
Dumping backwashed DE into storm drains where local rules prohibit it
Buying a new filter without first checking pump flow and pipe size

DE filters finest, then cartridge, then sand. Sand is simplest to maintain through backwashing, and cartridges use the least water.

Usually yes, in a standard sand tank. Use the reduced quantity the glass maker specifies and keep the same valve settings.
