The UNS CO2 Diffuser efficiently distributes CO2 throughout a planted aquarium by producing ultra-fine microbubbles that are easily absorbed by aquatic plants. Its precision cerami c disc creates consistent diffusion, helping improve CO2 efficiency and overall plant health. Made from durable, transparent acrylic, the diffuser blends cleanly into the aquarium while remaining sturdy during regular maintenance. It can be easily secured in place using the included suction cup and positioned to optimize circulation and distribution. Product Highlights- Ultra-fine CO2 diffusion!

Performance may vary slightly based on CO2 levels and placement within the tank. Usage & Maintenance- Soak diffuser in clean water for approximately 30 minutes before first use to prep the disc for finer bubble diffusion- If bubble size increases and output slows, soak in a diluted bleach solution for 10 minutes.
