1. Product Parameters: Dimensions: 20cm × 30cm × 2cm (7.9 × 11.8× 0.8in) Material: High-density polyurethane foam (PU) Structure: 8-layer design Safety: zero chemical adhesives Compatibility: Fits all internal/external filters (trim to size) 2. Key Selling Points: 🔹 Unbeatable Filtration Performance Unlike single-layer foams, our 8D aquarium filter sponge combines mechanical AND biological filtration: 🔹 Cut-to-Fit Freedom Tired of overpaying for brand-specific cartridges? Simply trim this pond filter foam with scissors to perfectly fit brand-specific or generic filter boxes. One sheet = endless custom sizes! 🔹 Zero-Clog Technology Ultra-porous cells (80 PPI) maintain full water flow even when dirty. Never slows your filter’s output or strains the motor – unlike cheaper foams that collapse. 3. Usage Scenarios: 🐠 For Tropical Aquariums Place in hang-on-back filters to stop cloudiness. Safe for community tanks (tetras/guppies) and sensitive biotopes (shrimp breeders swear by it!). 🐢 Turtle Tank Saviour Coarse mesh traps bulky waste from sliders/musk turtles. Rinse weekly; no disintegration from constant cleaning! 🔧 Filter Media Upgrade Layer beneath ceramic rings in canister filters. Maximises biological filtration surface area. 🌿 Aquascaper’s Secret Weapon Pre-filters inlet pipes in planted tanks. Stops soil/substrate from clogging impellers!
