The Chihiros stainless steel CO2 diffusers dissolve the CO2 running through them. Small CO2 bubbles are distributed in the tank and guarantee an optimal CO2 uptake by the water plants. The CO2 dissolves easily in the tank due to the fine dispersion of the Bubbles.

These CO2 diffusers come with two transparent suction cups, a 90 cm hose and a stainless steel clip are included.

The diffusors are made of 304 stainless steel wich looks great, is persistent, easy to clean, subtel yet pleasing to the eye.

When algae start forming on your diffusor or when larger and larger bubbles emerge from your ceramic diffusor it is time for cleaning. Stainless steel is easy to clean, however, it should be done diligently. After the cleaning process, your stainless steel products will be as good as new.

  • You'll need a household bleach containing chlorine without perfumes. When working with chlorine bleach, please make sure you absolutely observe the manufacturer's safety notes.
  • Pour some of the bleach into a container and mix with an equal amount of water. Mix so much of this solution that the products you wish to clean are entirely covered
  • Soak the Stainless steelware in the solution for 1 to 4 hours (depending on the severity of the stains)
  • Take it out and rinse thoroughly
  • Now all the stains ought to be gone, and your Stainless steel should shine as if new

You'll find an extensive how-to (in German) with pictures in our Aquascaping Wiki under Glaswaren reinigen.
