Why You’ll Love It The hygger Biochemical Sponge Filter delivers powerful 3-in-1 filtration—mechanical, biological, and aeration—while staying whisper-quiet and easy to maintain. Perfect for shrimp, bettas, fry tanks, nano aquariums, and large tanks for supplemental filtration, it combines a high-density sponge with a ceramic bio media chamber to keep water clean, stable, and well-oxygenated. Available in Small, Medium, and Large sizes to fit aquariums from 5 to 125 gallons. Key Features 3-in-1 Filtration System: Mechanical Biological Aeration The sponge traps debris and particles, while ceramic bio media supports beneficial bacteria to remove harmful ammonia and nitrites. Rising bubbles from the air pump simultaneously oxygenate the tank. Upgraded Biochemical Sponge High-density, non-clogging sponge captures waste, uneaten food, and fish debris without harming delicate fish or shrimp. Built-In Bio Media Chamber Strengthens biological filtration with included ceramic media, improving water clarity and long-term stability. Quiet & Energy Efficient Silent operation powered by an external air pump (not included). Ideal for bedrooms, offices, and breeding setups. Easy to Assemble, Clean & Maintain The filter disassembles quickly for maintenance. Simply rinse the sponge in tank water—no complicated steps. Great for Many Aquarium Types Suitable for: Shrimp tanks Betta tanks Breeding & fry grow-out tanks Nano aquariums Quarantine/hospital tanks Large tanks (as auxiliary filtration) Three Sizes for Choice Small: it works pretty well for filtration for 5-20 Gal small aquariums under 14″ depth with an air pump ≥ 1.5W. Medium: suggested for 20-55 Gal medium-sized aquariums under 19.7″ depth with an air pump ≥ 2W. Large: suggested for 55-125 Gal aquariums under 26.4″ depth with an air pump ≥ 5W. Usage Tips How It Works The air pump pushes air through the air stone. Rising bubbles create suction through the sponge. Sponge filters debris (mechanical filtration). Water passes through ceramic media (biological filtration). Clean, oxygen-rich water rises back into the tank. Note: 1. Rinse sponge every 2–4 weeks (based on bioload). 2. Works perfectly during power outages when paired with a battery air pump.
