It's sometimes tricky to know which products you should invest in for your proposed set up so we have taken the stress out of it and put a bundle deal together for you and thrown in a freebie. It consists of:

• CO2 diffuser suitable for aquariums up to 300L
• AE Design CO2 tubing - 2 meters
• Non return valve (free of charge!)
• 2 free suction cups

By investing in the AE Design Diffuser Set 300L you have all the equipment needed to attach to your CO2 bottle and regulator (not supplied) and you're ready to begin infusing CO2 into your planted aquarium.

Please note the diffuser may differ from the picture shown but it will still be suitable for aquariums up to 300L.

Directions for use:

Set up for this is simple. Using the supplied CO2 tubing, attach this to your existing regulator and then the set up should be

1. non return valve
2. bubble counter
3. diffuser.

After inserting your non return valve onto the CO2 tubing, cut approximately 3cm of tubing and attach it to the top of your non return valve. Your bubble counter will then attach onto that.

Fill your bubble counter with water and insert remainder of CO2 tubing onto bubble counter and on the end of your CO2 tubing, insert your diffuser. Your set up in now complete.
