Laguna PowerFlo Underwater Filter Foams, 2-Pack
Laguna Foam Media is specifically designed for use inside the Laguna Powerful Mechanical (PT-500) and Biological (PT-505) Underwater Filters. 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. Laguna Foam Media is a great way to help keep your pond environment clean and clear.
