PHOSGUARD 4 L

PhosGuard Seachem 4 L – Phosphate and Silicate Removal

PhosGuard is an aluminum oxide-based adsorbent media, specially formulated to effectively remove phosphates and silicates responsible for the proliferation of unwanted algae.

It acts quickly, without leaching, thanks to an irreversible binding of the targeted compounds.

Performance and Design

PhosGuard is presented in the form of highly porous spherical beads, ensuring optimal hydrodynamics and excellent water flow through the media.

This structure maximizes contact surface and improves adsorption efficiency, both in reef aquariums and freshwater.

Main Features

Recommended Usage

PhosGuard is particularly effective in marine aquariums, where managing phosphates and silicates is essential. It can also be used in freshwater, provided it is not phosphate-buffered.

It is used in small quantities, renewed regularly, which is preferable to occasional use of large quantities.

Instructions for Use

Before use, pre-wet PhosGuard by adding it to a double volume of freshwater, then rinse thoroughly.

Place the media in a high-flow area, without excessive movement, ideally in a media chamber, external filter, or trickle filter.

Use 85 ml of PhosGuard for 200 L of saltwater or 400 L of freshwater.

Let it act for about 4 days, then test phosphate or silicate concentrations. Replace the media if levels have not dropped below 0.02 mg/L.

Usage Tips

A too rapid drop in phosphate levels can cause temporary stress to corals. It is recommended to gradually adjust the quantities used.

PhosGuard does not regenerate and must be replaced once saturated.
