    25 Sq. Ft. Pleated Filter Cartridge for OceanClear & Nuclear Canister Filters Overview Upgrade or replace worn media with this 25 square foot pleated cartridge designed for high-capacity mechanical filtration in OceanClear and Nuclear-style canister filters. The rigid core and tightly pleated polyester provide a large surface area to capture fine debris while maintaining strong, consistent flow. Ideal for freshwater or marine systems where water clarity and polish are a priority. Key Features High Surface Area (25 sq. ft.) – Deep pleats maximize particle capture without excessive pressure drop. Durable Construction – Rigid center core resists collapse; heat-set pleats hold shape through repeated cleanings. Reliable Water Polishing – Traps suspended particulates to improve clarity in heavily stocked or high-flow systems. Easy Maintenance – Hose-rinse to restore flow; pleated design extends service life between changeouts. Freshwater & Marine Safe – Inert materials suitable for aquariums, ponds, and recirculating systems. Direct Fit – Sized for canisters that specify a 25 sq. ft. pleated element (OceanClear & Nuclear types). Product Specifications Media Type: Pleated polyester (mechanical filtration) Surface Area: 25 square feet Core: Rigid, collapse-resistant (non-metal) End Caps: Sealed to prevent bypass Compatibility: OceanClear and Nuclear canister filters that require a 25 sq. ft. pleated cartridge Recommended Use: Water polishing/clarification in freshwater or saltwater systems Care & Maintenance: Rinse with clean water as needed; replace when pleats no longer rinse clean or flow is restricted
