Dymax Pro-Lite Nano Biological Filter Media 4.8L

Dymax Pro-Lite Nano Technology biological filtration blocks provide an optimal living environment for beneficial micro-organisms in high bioload aquatic environments. Manufactured from natural silicate at high temperatures, each block features micro pores ranging from 60 to 300 micrometers, closely matching the structure of loose soil. This multi-porous design delivers six to eight times greater surface area than standard bio-rings, enabling both aerobic nitrification and anaerobic denitrification to effectively break down ammonia, nitrite, and nitrate. Suitable for freshwater aquariums, marine systems, and ponds, this 4.8-liter pack treats up to 1,000 liters of water and works reliably in trickle, canister, sump, and top filter configurations.
