CHEMICAL FILTRATION - SEACHEM PHOSGUARD 500ML
The Seachem PhosGuard 500ml is a highly porous filter media that effectively combats the two main factors causing algae in aquariums: phosphates and silicates. Its rapid action transforms water quality in just a few days.
Key Benefits
- Rapid elimination of phosphates (PO4)
- Absorption of silicates (SiO2)
- Effective fight against brown algae (diatoms)
- Compatible with marine and freshwater aquariums
- Particularly effective in saltwater
- Does not alter other water parameters
For which aquarium?
Recommended primarily for reef aquariums where phosphate control is crucial for coral health. Also very effective in freshwater aquariums overgrown with diatoms after startup.
L'Atelier's advice
Place the PhosGuard in a filter bag in a high-flow area of your sump or external filter. Replace it every 2 to 3 months depending on the phosphate load. Test your PO4 regularly to adjust the quantity used.
