The very latest style of inline CO2 diffusers are now available with Aqua Essentials. If you're fed up with glass diffusers or want something that you can fit inline to your external filter then this could be the perfect match for you.

It's so easy to use, simply attach it inline to your external filter piping (outlet tube) and then attach your CO2 tubing to the top part of the UP CO2 Inline Diffuser and that's it.

The filter tubing will fit snugly to this piece of CO2 equipment and what's more it means another piece of equipment outside of your tank so you can focus on your aquascape.

Effective and subtle, once you have used this inline CO2 diffuser, you won't turn back.
