Achieve "crystal clear" water with the Aqua One White Wool Pad (40W). These genuine replacement pads are designed for the Aquis 1000/1200 and Vaal 650/750 canister filters. As the final stage in your mechanical filtration process, the white wool pad acts as a fine polisher, trapping the microscopic particles that sponges often miss.
Because of its dense, fibrous structure, the wool pad is essential for removing the "cloudiness" from your aquarium water, leaving it sparkling and clean.
Fine Particle Polishing: Traps very fine suspended debris, silt, and waste particles to provide maximum water clarity.
Final Stage Mechanical Filtration: Positioned at the end of the filtration cycle, it ensures that water returning to the tank is free from visible impurities.
Genuine Aqua One Part: Specifically cut to fit the filter baskets of the Aquis and Vaal series perfectly, preventing "water bypass."
Safe for All Environments: Suitable for both freshwater and saltwater aquariums.
Value Pack: Includes 2 white wool pads per pack (Part #40W).
Part Number: 39W
Colour: White
Quantity: 2 Pads per pack
Compatibility: * Aquis: 1000, 1000 Series II, 1200, 1200 Series II
Vaal: 650, 750
Unlike the blue or black sponges, White Wool pads are disposable and should not be washed and reused. Once the pad becomes brown and compressed, it has reached its capacity and should be replaced (typically every 4–6 weeks) to maintain optimal water flow and clarity.
