How much pressure do I need?

You need at least 1.5 bar working pressure for this diffuser to work properly. The PlantedBox aquarium pressure regulator is perfect for that!

How should I connect the diffuser?

Soften a 4/6mm CO2 hose by putting it in a glass of boiling water for 30 seconds. Then carefully slide the hose over the connection of the diffuser. When doing so, never push on the “bend” but hold the connection of the diffuser in between your fingers.

Does it work much finer than a classic diffuser?

Yes, this diffuser uses a different membrane so the bubbles are a much much finer and appear all over the surface of the diffuser.

Does the diffuser need to soak for a few days first?

The Pro CO2 diffuser works optimally after 24 to 48 hours in the water.

How should I maintain the diffuser?

When doing water changes, you can put it in a solution of 1 part bleach to 10 parts water for half an hour. Then rinse it very well and put it back.
