Biological filter media sera Siporax algovec Professional 500 ml (210 g) for aquarium filtration and algae control

sera Siporax algovec Professional 500 ml (210 g) is a biological filter medium designed for aquarium filtration and algae control. The product is supplied in a compact container and combines a highly porous carrier material that supports the colonisation of beneficial nitrifying bacteria with surface properties that help limit unwanted algae development. It is suitable for placement in canister filters, internal filters and other biological filtration systems where stable biological filtration and improved water clarity are required.

Advantages

The porous structure of the media provides a large surface area for bacterial colonisation without releasing fines into the filter. Its formulation supports efficient nitrification to help stabilise the nitrogen cycle and contributes to improved water quality. The algal-control characteristic helps reduce visible algal growth on filter media and in filtration housings, assisting routine maintenance. The compact granules are mechanically stable and compatible with common aquarium filter types.

Suitable for

• Freshwater and marine aquariums requiring biological filtration
• Canister filters and external filtration systems
• Internal filters and wet/dry or trickle filters
• Setups where reduced algae growth on filter media is desired

Key specifications

• Format: 500 ml container (net weight 210 g)
• Material type: porous biological carrier designed for bacterial colonisation
• Function: supports nitrifying bacteria and has algal-control properties
• Compatibility: suitable for use in various aquarium filtration systems
• Particle form: small granules for even flow and mechanical stability

How to use

Rinse the media briefly with aquarium water before first use to remove any dust from transport; do not use tap water with strong chlorine treatment. Place the media in the designated chamber of the filter where water flow ensures contact with the carrier surface but avoids direct compression of the granules. Introduce the media together with an established biological filter batch when possible to accelerate colonisation by beneficial bacteria. Monitor water parameters regularly after installation and allow time for biological processes to stabilise.

Usage recommendations

Use the product as part of a complete filtration strategy together with mechanical and chemical filter stages as needed. Replace only a portion of the media at a time to preserve established bacterial colonies and avoid abrupt changes in biological load. Observe aquarium water quality and adjust maintenance intervals based on stocking density and feeding levels.
