The AQUARIO NEO CO2 Diffusor Curved Special is an acrylic CO2 Diffusor that brings the features of the NEO Special Type and upgrades them with yet another smart attribute. It is equipped with a very narrow diffusor body and the connection to the pipe at its side. This special small design ensures a fine integration of the diffusor into small and nano tanks. The particular ceramic membrane produces a fine mist and the CO2 gets dissolved very quickly. Moreover, this diffusor has curved tube ends which make it easy to hang the diffuser over the edge of the tank so that unattractive hoses do not disturb the eye anymore.


For finest bubbles it is advisable to put the diffusor into water for 10 minutes, so that all membrane pores get soked completely. If the bubbles get bigger with time, you can clean the membrane with bleach. You will find a detailed describtion below.
