Ubbink Pond Filter Material Lava Volcanic Rock 16-32 Mm 10 L

Keep the water in your pond clean and clear with this 10 liter volcanic stone Lava natural pond filter material from Ubbink. These natural granules work as an effective filtering agent and promote a healthy and balanced ecosystem.

• Quick clarifying effect: lava is a natural volcanic rock for biological filtration. The granules or fragments therefore have different sizes, varying in diameter from 16 to 32 mm. They quickly turn cloudy water into a crystal clear oasis.
• Maximum bacteria-adhesive surface: the structure, which is both rough and porous, offers the best colonization conditions for bacteria to quickly establish a healthy bacterial colony in pond water.
• Handy 10 L packaging: Ubbink's pond filter granules are supplied in a handy 10 L packaging. They act as nature's purifiers, helping to remove contaminants and contributing to the general well-being of your pond's inhabitants.

Good to know:

• The Lava pond granules must be placed in a net in the pond filter installation, between the foam filters with mechanical action and the filter material with biological action.
