Sustainable phosphate removal for fresh and salt water — active for up to 3 months
Sera Phosvec Granulat — filter material for effective phosphate removal
✅ Level: Easy — Simply place it in the filter. No special knowledge required.
Phosphate is only needed in small quantities as a nutrient for plants — at higher concentrations, it causes stubborn algae growth. Sera Phosvec Granulat easily and safely removes phosphate from aquarium water with a long-lasting effect of up to 3 months. Suitable for use in fresh and salt water filters.

✂️ Usage tips
Place the granulate in a filter net or filter holder in your external or internal filter. Replace after a maximum of 3 months or earlier if the phosphate level rises again. Use the Sera PO₄-Test to monitor the effect and determine the correct replacement time.
💡 Tip
Combine Phosvec Granulat with regular water changes and less feeding for the best results in persistent algae problems.
