CO2 diffusers efficiently distribute CO2 in a planted aquarium tank. Zephyr by Aqua Worx features tiny holes that work to produce a very fine mist and thorough bubble diffusion. The microbubbles produced are diffused throughout the aquarium tank, effectively allowing aquatic plants to absorb CO2 properly and reflect lush growth. Built from extremely durable materials, the Zephyr CO2 diffuser for planted aquarium tanks is shatterproof and will not break during routine aquarium tank maintenance. Its clear body and simple design integrates well into planted aquarium tanks and lessens potential viewing distraction caused by aquarium tank equipment. Similar to other diffusers, users are able to place it in the corner of a planted aquarium tank securely with the provided suction cup. We recommend placing it directly across the aquarium filter to ensure CO2 is pushed throughout the water column efficiently and effectively.

Aquarium tank lighting and CO2 injection go hand-in-hand! If either level is off, pesky algae will have the opportunity to strike. Check out Aqua Worx's aquarium LED lighting by clicking here

- Soak the diffuser in water for 30 minutes before use to produce smaller bubbles.
