Filtration media 12 styles to choose from Substrate for internal/external filter

Specifications :

• Filtration media 12 different types to choose from
• Color/shape: see pictures
• Weight: 50g/250g/500g for choice

Features:

• Activated carbon: water sterilization and purification, odor removal
• Aerator rings: emit infrared rays to improve oxygen and nutrient uptake by aquarium creatures
• Ammonia eliminators: their structure promotes the growth of biobacteria and allows the absorption of harmful substances
• Coral sand: sourced from marine corals, it absorbs harmful bacteria and greatly promotes the growth of nitrobacteria
• Maifan gravel: it is an ore close to volcanic rocks in constitution, can release oxygen, purify water and absorb chlorine and other toxic substances
• Ceramic noodles: unique structure promoting the growth of nitrifying bacteria
• Volcanic rocks: absorb toxic substances and heavy metals in the water with their special porous structure and stabilize the quality and pH of the water
• Bacterial rings: the large number of micro-pores allows for larger colonies of biobacteria, which can break down nitrites and nitrates more quickly
• Quartz balls: long-term pH stabilization, absorption of toxic factors
• Porous biospheres: improve fish metabolism and facilitate the elimination of toxic substances in the body, increase the oxygen content and activate water molecules
• Biochemical balls: Their porous structure provides a habitat for nitrobacteria. Improve filtration and therefore water quality
• Nano-bacterial rings: their surface is covered with micro-pores for a higher colony density of nitrobacteria
