PowerFlo Underwater Filter Foams PT-550
Laguna Foam Media is specifically designed for use inside the Laguna PowerFlo Underwater Mechanical Filter (PT-500) and the Laguna PowerFlo Max Underwater Biological Filter (PT-505).
The coarse foam material performs mechanical filtration, capturing dirt and debris as water flows through it. The foam is also porous to allow some degree of biological filtration. Includes two foam inserts.
