Product Overview The Qanvee Sponge Filter is a highly efficient, air-driven mechanical and biological filter engineered with dual media chambers for planted aquariums and breeding setups. Sponge filters are exceptionally good for shrimp tanks because they buffer flow into a gentle, controlled current while ensuring baby shrimp and fry never get sucked into the filter. Powered by an air pump, the dense foam traps floating detritus and provides a vast surface area for nitrifying bacteria. Setup Requirement: Requires an aquarium air pump, filtration media, check valve, and standard 3/16" airline tubing (sold separately). Key Features & Benefits Safe for Dwarf Shrimp & Fry: Soft foam intake buffers water current and prevents newly hatched shrimp fry and nano fish from getting pulled into the filter. Dual Media Chambers: Includes two refillable bottom compartments to house additional ceramic rings, bio-balls, or chemical filtration media. High-Density Mechanical Foam: Traps floating plant matter, fish waste, and uneaten food while serving as a natural grazing surface for shrimp. Biological Bacteria Haven: Porous foam cell structure fosters massive colonies of beneficial nitrifying bacteria to cycle ammonia and nitrites. Adjustable Telescopic Outlet: Features an extendable uplift tube to customize water return height and maximize surface aeration. Technical Specifications Always rinse filter sponges in drained aquarium water to protect beneficial bacteria colonies.

Why are Qanvee sponge filters ideal for dwarf shrimp tanks?Sponge filters eliminate harsh intake suction that can trap or kill tiny shrimp fry. Additionally, dwarf shrimp love grazing on the beneficial micro-organisms, algae, and biofilm that naturally collect on the large foam surface area. 2. How do I clean my Qanvee Sponge Filter during maintenance?Squeeze and rinse the sponges in a bucket of drained aquarium water during routine water changes. Avoid using chlorinated tap water, as it will kill the beneficial nitrifying bacteria residing inside the sponge pores.
