PhosGuard 1 L Seachem - phosphate and silicate filtering media for aquariums

PhosGuard is a spherical aluminum oxide filter media designed to quickly reduce phosphate and silicate concentrations in marine and freshwater aquariums. Its porous structure promotes a smooth water flow and efficient adsorption of undesirable compounds.

Main features

Advantages and functioning

PhosGuard acts by directly adsorbing phosphate and silicate. It is not an exchange resin and does not release any substances into the aquarium water. The media can be removed, dried, and then reused until fully saturated. Continuous use of small amounts allows for more stable control of parameters than an intensive one-time treatment.

Instructions for use

PhosGuard may generate heat upon initial contact with water. It is recommended to pre-soak the media in a double volume of fresh water, then rinse it before use. Install the product in a high-flow area to optimize water flow through the media, without any tumbling effect.

It can be used in a cartridge filter, a media chamber, a canister filter, or any high-flow area of a trickle filter. The use of a filter bag is recommended.

Recommended dosage: 85 ml for 200 L of saltwater or 400 L of freshwater.

Leave the media in place for 4 days, then test for phosphate or silicate. If the concentration remains above 0.02 mg/L, replace the media. Otherwise, leave it in place until the parameters increase again.

Frequently Asked Questions

Duration of effectiveness and saturation

In an aquarium with high phosphate levels, PhosGuard can become saturated in 4 to 5 days. It is advisable to regularly test the parameters and replace the media as soon as the concentrations stop decreasing.

Media regeneration

Aluminum oxide-based media are not regenerable by heating. The phosphate chemically bound to aluminum oxide cannot be released by this process.

Under normal reef conditions, no detectable release of soluble aluminum is observed. However, a rapid decrease in phosphate can temporarily cause a closure of the corals, hence the importance of avoiding any overdose.

Reactor media usage

The use in a media reactor is not recommended, as the tumbling motion can generate dust from the media.
