Fluval Foam Filter Block
Fluval Foam Filter Blocks are recognized for their dense, uniform pore structure and precise sizing that makes them ideal for reliable mechanical and biological filtration when replacing foam media pads. They hold a best-in-class position because they combine long lifespan and consistent flow with competitive pack pricing, offering a lower cost-per-use compared with some premium OEM foams like Seachem while providing more structural integrity than cheaper generic inserts.
