Filter media sera Siporax algovec Professional 35 g — anti-algae biological carrier for aquaria

sera Siporax algovec Professional 35 g is a purpose-made filter media for aquaria, formulated to support biological filtration while helping to reduce algae proliferation. The 35 g pack contains porous Siporax carrier material that provides a high surface area for colonization by beneficial nitrifying and denitrifying bacteria. It is suitable for use in internal and external filters in both freshwater and marine setups and is intended to assist with maintaining water quality and stabilizing the aquarium ecosystem.

Advantages

The porous structure of the Siporax media offers extensive surface area for microbial biofilms, improving nitrification and organic decomposition. The algovec formulation is designed to limit conditions that favour algal overgrowth without introducing chemical additives into the water. The compact 35 g quantity is convenient for targeted treatment zones in small filters or as supplemental media in larger filtration systems. The media is physically stable, rinsable, and compatible with common aquarium equipment and established biological filter environments.

Suitable for

• Freshwater aquaria with light-induced algal issues
• Marine and reef systems requiring biological filtration support
• Internal and external canister filters as supplementary media
• Small tanks and quarantine setups where a compact media dose is needed

Key specifications

• Content: 35 g of porous Siporax carrier material
• Material type: high-surface-area ceramic/porous substrate for biofilm
• Intended effect: supports beneficial bacteria and helps reduce algal growth
• Compatibility: suitable for freshwater and marine aquarium filtration systems
• Application form: loose granular media for placement in filter chambers or media bags

How to use

Rinse the media briefly with dechlorinated aquarium water to remove dust before placement. Place the Siporax algovec media in an appropriate compartment of an internal filter, external canister, or a fine-mesh media bag in the filter flow path to ensure steady water contact. Use the full 35 g package in small tanks or as a supplemental layer in larger setups. Maintain normal filter flow and biological cycling; do not use with strong chemical algicides or continuous high doses of oxidizing agents which can disrupt beneficial bacteria.

Usage recommendations

Monitor water parameters regularly after introduction—check ammonia, nitrite and nitrate levels—and observe algae coverage over several weeks to assess effectiveness. Replace or gently rinse the media as part of routine filter maintenance if excessive detritus accumulates; avoid aggressive cleaning that would remove established biofilm. Combine the media with appropriate light management and routine aquarium maintenance for best results.
