Sponge Aquarium Filter for 20 Gallon Tall Shrimp Tanks, 35 PPI Matten Foam and Lift Tube Set

Create a broad biological filtration wall in a 20-gallon tall freshwater shrimp tank with this Matten-style sponge aquarium filter. Its large foam surface gives beneficial bacteria room to colonize and provides shrimp and young shrimp with an area where naturally occurring biofilm can develop.

The 35 PPI black reticulated foam is fine enough to reduce the risk of shrimp becoming trapped. A lift tube moves water from lower in the tank toward the top for gentle circulation, while the broad filter surface is listed at two to four times that of typical sponge filters.

Key Features

• Wall-style Matten foam creates extensive surface area for beneficial bacteria.
• Thirty-five PPI structure is designed with small shrimp in mind.
• Lift-tube flow supports top-to-bottom circulation in a freshwater tank.
• Large foam area offers shrimp a surface for grazing on developing biofilm.
