Ensure your canister filter performs at its best with the Aqua One Blue Sponge Pad (40B). These genuine replacement sponges are designed for the Aquis 1000 and 1200 Canister Filters. As the "coarse" stage of your filtration system, the blue sponge is your first line of defense against larger waste particles.
With a 15ppi (pores per inch) rating, this sponge features larger pores than the black or white pads. This design allows for maximum water flow while successfully trapping heavy debris before it can clog your finer filter media.
Coarse Mechanical Filtration: Specifically designed to trap large organic matter, uneaten food, and plant debris, preventing the rest of your filter from clogging prematurely.
Essential Biological Support: The large surface area provides a stable environment for beneficial bacteria to colonize, helping to neutralize ammonia and nitrites.
High Flow Rate: The 15ppi density ensures that water moves through the canister with minimal resistance, maintaining the high oxygen levels necessary for a healthy tank.
Genuine Replacement (Part #40B): Guaranteed to fit perfectly into the filter baskets of the Aquis 1000 and 1200 series, ensuring no water bypasses the filtration stages.
Freshwater & Saltwater Safe: Made from high-quality, inert foam that will not affect your water parameters.
Part Number: 40B
Density: 15ppi (Coarse)
Colour: Blue
Quantity: 2 Pads per pack
Compatibility: Aquis 1000, Aquis 1000 Series II, Aquis 1200, Aquis 1200 Series II
Because the blue sponge catches the largest debris, it often gets dirty the fastest. During your regular filter maintenance, rinse the sponge thoroughly in a bucket of aquarium water to remove sludge while keeping the "good" bacteria alive. Replace the sponge every 6–12 months or when it no longer returns to its original shape after cleaning.
