Description
The 15 D Sponge Foam (12×15) is a high-density, multi-layer biochemical filter media designed for superior water purification in both freshwater and marine aquariums. The “15D” designation refers to its advanced high-density structure, which is often an upgrade over standard 8D or 12D sponges, providing more layers for finer filtration.Key Product FeaturesHigh-Density Filtration: Features a 15-layer (or 15D density) honeycomb structure that effectively traps fine debris, fish waste, and uneaten food while maintaining high water permeability.Biochemical Surface: The porous design provides a massive surface area for the colonization of beneficial nitrifying bacteria, which are essential for breaking down harmful ammonia and nitrites.No-Glue Construction: Manufactured using high-temperature hot-melt technology rather than chemical adhesives, making it non-toxic and completely safe for sensitive fish and shrimp.Cut-to-Size Versatility: The 12×15 inch (approx. 30×38 cm) sheet can be easily trimmed with scissors to fit any filtration system, including:Canister filtersSump systemsHang-on-back (HOB) filtersPond filtersDurable & Washable: Built to withstand repeated cleaning without losing its shape or clogging easily. It can be rinsed and reused over 300 times.Usage and MaintenancePreparation: Soak the sponge in aquarium water for about 5 minutes before the first use to help beneficial bacteria colonize more quickly.Cleaning: Always rinse the sponge in room-temperature aquarium water (not tap water) to preserve the live bacterial colonies. Avoid using hot water, which can damage the foam structure.Placement: Place it as the final mechanical stage or primary biological stage in your filter to polish the water and ensure maximum clarity.
