Aquarium Equipment — Biochemical Sponge Filter Series

Biochemical Sponge Filter
Aquarium Bio Filtration

✦ Bio Filter · Skimmer · 360° Adjustable · Silent · Suction Mount

Clean water is healthy fish. This biochemical sponge filter combines mechanical and biological filtration in one compact unit — trapping debris while hosting the beneficial bacteria colonies your tank needs to stay balanced. Silent, easy to clean, and air-pump driven for gentle, consistent water circulation.

🧪 Dual Biochemical Filtration

Provides both mechanical filtration (trapping debris) and biological filtration (hosting nitrifying bacteria) — maintaining stable water quality and a healthy nitrogen cycle.

Biological filtration — stabilises water quality
Increases oxygen solubility in tank water
Good permeability — maximum water flow through sponge
Easy to clean — rinse & reuse repeatedly

🔇 Silent 360° Adjustable

Works noiselessly via air pump connection — no motor noise, no vibration. The 360° adjustable head lets you direct water flow exactly where your tank needs it.

Silent operation — air pump driven
360° adjustable head — directional flow control
Suction cup mount — sticks to smooth glass/acrylic
Compact design — suits small to medium tanks
