EHEIM Substrat Pro Biological Filter Media – Sintered Pearl-Shaped Glass 1L

About EHEIM Substrat Pro

Designed for aquarium filtration, EHEIM Substrat Pro leverages sintered pearl-shaped glass to create an open, highly porous structure that encourages smooth water throughflow and robust surface colonization by beneficial bacteria. In real-world setups, this combination can help maintain clearer water and a more stable bio-film within your filter.

Key design benefits

• Made of highly porous artificial sintered glass for durability and performance.
• Unbeatable surface area: 1800 sq ft per gallon, maximizing contact with water.
• Reusable by lightly rinsing with aquarium water every 1–3 months and replaced every 3–6 months.
• Provides longer intervals between maintenance tasks by supporting efficient biology.
• Works with all EHEIM filters (Classic, Ecco, Pro 3, Pro 3e).

Real-life use and benefits

In daily aquarium care, Substrat Pro helps water circulate more evenly through the filter media, reducing stagnant zones. The open structure supports healthy bacterial growth while keeping debris in check, contributing to clearer water and a more stable environment for aquatic life.

How to use and care

• Rinse gently in aquarium water to remove dust before placing in the filter.
• Reuse for 1–3 months; replace every 3–6 months for optimal performance.
• Ensure the filter is powered down during handling and reassembly.

Compatibility and notes

Designed for use in EHEIM Classic, Ecco, Pro 3, and Pro 3e filtration systems, Substrat Pro integrates with existing setups for a straightforward upgrade of biological media. Results depend on tank size, stocking, feeding, and routine maintenance.
