Dicalite Minerals DE25BOX Diatomaceous Earth Pool Filter

Dicalite DE25BOX provides a natural, highly efficient filtration medium designed for both above-ground and in-ground DE filter systems. This high-grade DE powder enables filtration down to approximately 3–5 microns, delivering very clear water while reducing the need for chemical adjustments when used correctly. Consider compatibility with your DE system, recommended handling procedures, and regular backwashing schedules to maximize performance and lifespan of your filtration setup.
OptiFlow Pool Filter Sand, 50 Lbs

OptiFlow Filter Sand uses a pure silica formula with angular grains crafted to enhance filtration efficiency. The result is longer-lasting filtration performance and clearer water. This media is designed to support strong water flow and reduce backwashing frequency, improving overall pool maintenance and conserving water. Before switching media, verify compatibility with your filter tank and backwashing schedule to maintain optimal flow rates.
Intex 29002E Type A Pool Filter Cartridge (Two Pack)

This two-pack of Type A filter cartridges is designed for use with specific Intex Krystal Clear cartridge filter pumps. Its Dacron-based filtration media simplifies maintenance and replacement, supporting reliable filtration for above-ground pools. Regular replacement every two weeks helps sustain water clarity and pump efficiency, especially in high-use seasons or warmer climates where debris and oils accumulate quickly.
HTH 67227 Pool Care Filter Cleaner

HTH Filter Cleaner is designed to quickly rejuvenate a clogged filter by removing gunk that reduces filtration efficiency. Suitable for all major filter types—including cartridges, D.E., and sand—the cleaner is applied in the evening and left to work overnight. Regular use can help maintain filtration efficiency and extend the life of the pool’s filtering system, especially when paired with routine maintenance and compatible chemical balance.
HTH 67121 D.E. Filter Aid

HTH D.E. Filter Aid is designed to enhance the performance of DE filters by improving direct filtration efficiency and water clarity. It’s compatible with all DE filters and suitable for saltwater systems, making it a flexible option for varied pool setups. Use as directed, ensuring even distribution and appropriate dosing to avoid overloading the system or impacting best-available water balance.
DPM Celatom Diatomaceous Earth Pool Filter Powder

Celatom DE powder by DPM EP Minerals is a world-renowned filter media option for pools and spas. It captures even the tiniest particles down to 2 microns, providing strong water clarification and helping reduce chemical usage when paired with balanced chemistry. This media is widely regarded for its cleaning efficiency and compatibility with traditional DE filter systems, supporting sparkling pool water when used correctly.
Buying Guide: Key Purchase Considerations
- Filter type compatibility: Confirm whether your system uses DE, sand, or cartridge media, and verify that the chosen product matches your filter’s design and backwash requirements.
- Filtration micron rating: DE media typically offers the finest filtration (sub-micron range), followed by cartridge media and then silica sand. Higher filtration granularity often means better water clarity but may require more maintenance.
- Maintenance and backwashing needs: Sand and DE media affect backwash frequency differently. Cartridge filters generally require cartridge replacement on a schedule rather than backwashing. Consider your maintenance capacity and water-use goals.
- System compatibility and saltwater use: Some products explicitly support saltwater systems, while others are designed primarily for freshwater setups. Check compatibility with your pool chemistry and pump model.
- Cost of media and replacement parts: Compare upfront costs, replacement frequencies, and any added maintenance products (like filter cleaners) to determine total cost of ownership over a swimming season.
- Water clarity goals: For ultra-clear water, DE media provides the finest filtration. For easier maintenance and moderate clarity, high-quality sand or cartridge media can be sufficient depending on pool usage and debris load.
- Environmental considerations: Some DE powders are more environmentally friendly or easier to handle. Follow safety guidelines for handling and disposal as directed by manufacturers.
- Installation and performance notes: Proper dosing, distribution, and adherence to manufacturer guidelines are essential to avoid damage to filters and to optimize performance across media types.
