Petzlifeworld CO2 Super Diffuser V-AP-007 Aquarium Tool

This Super CO2 Diffuser’s specialized ceramic membrane ensures that the CO2 dissolves very well in the water, as it produces a great number of very fine bubbles. For best results it is recommended to position the diffuser just above the substrate and beneath the outflow from your filter. This gives the CO2 bubbles maximum time as they rise to the surface, and are then dispersed around the aquarium as they enter the water flow from the filter, further extending the time the CO2 is in the water and can be diffused. Features It hides well It produces ultra-fine bubbles We recommend this diffuser for up to 3-6 feet of aquarium.
