A professionally designed glass diffuser for planted aquariums upto 180 litres.
Watch the bubbles rise through the glass ladder and then pass through the ceramic plate at the top of the diffuser.
The benefit with this diffuser is CO2 spends a maximum amount of time diffusing into the water even before it has left the ceramic plate, making it an economical diffuser to have in your aquarium
Tips
Don not try and fill your diffuser up with water to begin with. It will fill up on its own
In addition, the CO2 bubbles will not travel up the spiral until the water has filled the spiral (this can take a few days)
