The biological reduction of nitrates (NO3) & phosphates (PO4) supports the natural activity of bacteria to eliminate excess nutrients, providing crystal-clear water and stable water parameters. It is ideal for preventing algae.

Includes a advanced carbon source blend that enhances nitrification and denitrification, improving filter bacteria performance and promoting the natural breakdown of phosphates. Enables nutrient control without chemicals.

Safe for corals and sensitive species such as shrimp and decorative fish, it does not cloud the water, cause pH changes, or leave harmful residues. Suitable for all types of aquariums.

The dosing system is simple, starting with 2 ml per 100 L daily, gradually increasing to 10 ml. Visible results are observed within a few days and it works perfectly with the ARKA Basic N & P nutrient system.

The ARKA system solution for system care replaces separate nitrate and phosphate removers, and is trusted by hobbyists worldwide. Available in 118 ml, 473 ml, and 5000 ml for sustainable, professional water management.
