| This BioChem Zorb cartridge is included with all Rena Nexx and SmartFilter aquarium filters. The four-sided cartridge has two layers of mechanical filtration and an inner layer of BioChem Zorb which is a mixture of activated carbon, ammonia removers and scavenger resins. This is the best combination of chemical and mechanical filtration for most aquariums. Coming soon for the Nexx and SmartFilter, NitraZorb cartridges and PhosZorb cartridges for those wanting to customize the Nexx and SmartFilter cartridge system to suit an aquarium's particular water quality needs. |
