## Overview

Seachem PhosGuard is a 4L premium filtration media designed to rapidly and irreversibly remove phosphate and silicate from both marine and freshwater aquariums. Its highly porous, bead-shaped form maximizes water flow and filtration capacity, ensuring sustained water clarity and health. Ideal for professional aquarists seeking reliable, high-performance water purification.

## Description

PhosGuard™ rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate buffered freshwater. PhosGuard™ is highly porous for high capacity and bead-shaped for optimum water flow.

## Features

- REMOVES SILICATE AND PHOSPHATE: PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquaria.
- IRREVERSIBLE BINDING: PhosGuard will not release phosphates or silicates back into your tank or aquarium due to its ability to exhibit strong binding capabilities, consequently reducing phosphates and silicates to very low levels.
- USE: Although PhosGuard is effective in both fresh and marine water, it will provide optimal results in sea water and the need for it is better defined in sea water.
- FILTRATION: PhosGuard is highly porous and bead-shaped to promote easy water flow through and around it, increasing both its efficiency and capacity.
- DIRECTIONS: Use 85 mL (⅓ cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. For best results, PhosGuard should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow.
