CHEMICAL FILTRATION - SEACHEM PHOSGUARD 250ML
The Seachem PhosGuard 250ml is a highly porous filter media designed to quickly remove phosphates and silicates from your water. Ideal size for small to medium aquariums, or as a supplement to existing filtration.
Key Benefits
- Rapid removal of phosphates (PO4)
- Absorption of silicates (SiO2)
- Prevention of brown and green algae
- Compatible with fresh and saltwater
- Maximum effectiveness in saltwater
- Convenient 250 ml size
For which aquarium?
Perfect for nano-reefs or aquariums under 200L where a larger size would be overkill. Also ideal for testing the effectiveness of PhosGuard before investing in the 1L size.
L'Atelier's advice
Use PhosGuard in a filter bag (not included) in your external filter or sump. Rinse it with RO water before use to remove dust. Monitor your parameters: if phosphates remain at 0 for too long, remove the product (corals need them in small quantities).
