Lee’s Wooden Air Diffusers – 2″ – 2 pk

Carefully hand cut against the grain, Lee’s Wooden Air Diffusers produce super fine bubbles which are released from all-natural lime wooden micro pores. This increases the efficiency of air-driven protein skimmers, or foam fractionators. These diffusers are beneficial for your aquatic life, as they provide excellent water circulation which increases the oxygen levels in your aquarium.
