How the CO2 Micro-Perler works
The CO2 supplied by the CO2 fertilizer system is forced through the micropore filter tube, thereby forming thousands of tiny CO2 bubbles that quickly and effectively dissolve in the steady flow of water. The CO2-enriched water then enters the aquarium through the filter return line.
Other gases that occur naturally in the aquarium water – so-called waste
gases – are also carried along. However, these do not dissolve, but form
small bubbles that are automatically expelled by the filter.
Aquarium size and suitable external filters
Given normal CO2 requirements, the Micro-Perler Special can supply aquariums of up to 400 liters. The device is ideally suited for use with all external filters with a water flow from bottom to top and a minimum water output of approx. 100 liters/hour., i.e. for practically all standard models.

In the case of filters with an output in excess of 400 liters/hour, we
recommend connecting two Micro-Perlers Special (see Fig.).
