Product details
Seachem PhosGuard 100mL Bagged (185) is a Seachem water-care media designed to rapidly remove phosphate and silicate from aquarium water. It’s used to help control dissolved nutrients that can contribute to nuisance algae and to support clearer, more stable water conditions in both marine and freshwater aquaria. As a group-level guidance, it is generally described as operating better in saltwater, while phosphate buffered freshwater is not recommended because it can remove the buffer until the media is saturated.
Features:
- Rapidly removes phosphate and silicate from aquarium systems
- Works in both marine and freshwater, with stronger expected performance in sea water
- Irreversibly binds phosphate and silicate to the media
- Highly porous, bead-shaped/spherical form helps promote water flow around and through the media
- Designed for efficient adsorption capacity due to its porous structure
Specifications:
- Form: Bagged media
- Size: 100 mL
- Basis: Alumina oxide (PhosGuard)
- PO4 binding: 0.87 mg/g (PO4 bound)
- Target compounds: Phosphate and silicate
- Use note: Not recommended for phosphate buffered freshwater; may remove the buffer until saturated
