Biohome Sump Brick - Filter Media

Biohome Sump Brick – High-Performance Sintered-Glass Filter Media (≈1.2 kg)

Upgrade your biological filtration with the Biohome Sump Brick, a premium filter media crafted from durable sintered glass. Measuring approximately 21 × 10 × 4.5 cm and weighing at least 1.2 kg, it offers extreme porosity and long-lasting performance—perfect for sump-based filtration in both freshwater and marine systems.

Key Features & Benefits

• Extremely high porosity (>50%): Draws water up the brick instantly, providing massive surface area for beneficial bacterial growth
• Supports full-cycle biofiltration: Encourages aerobic nitrifying bacteria (ammonia/nitrite) and anaerobic denitrifying colonies (nitrate) to thrive
• Robust industrial-grade build: Resists crumbling and withstands long-term water and flow exposure
• Inert material: Doesn’t affect pH or water chemistry—ideal for sensitive setupsIdeal Use & Dosing

• Use ~1 brick per 150 L tank water for effective nitrate reduction in average setups
• For heavily stocked or reef tanks, increase to 1 brick per 75 L for full-cycle filtration
• Place in sump or custom filter with moderate flow; add mechanical pre-filtration to reduce clogging
• Rinse lightly before use; avoid dropping the brick to maintain integrity
