The filter cartridge is filled with zeo carbon, a highly effective
filter substrate combination of high-quality activated carbon and particularly pure zeolite.
It removes odours, medication residue, chlorine and organic waste products caused by conversion. It further lowers the phosphate and ammonia content and ensures rapid growth of the bacteria culture, which promotes biodegradation.
These positive properties inhibit algae growth, create clear, non-toxic water, thus optimising species-appropriate care of the aquarium inhabitants and plants.
