PHOSGUARD 100ML

PhosGuard 100 ml Seachem – removal of phosphate and silicate in marine aquariums

PhosGuard is a filter media specifically developed to effectively reduce phosphate and silicate concentrations in marine and freshwater aquariums. Its highly porous structure and spherical shape ensure optimal water flow, increasing the contact surface and absorption speed.

Main Features

Advantages and Functioning

PhosGuard acts quickly by irreversibly binding phosphate and silicate, without releasing them back into the water. Unlike exchange resins, this media does not release any compounds into the aquarium. Its bead shape promotes even flow, preventing dead zones and maximizing treatment efficiency.

Dosage and Setup

Before use, PhosGuard should be pre-moistened in freshwater and rinsed to remove any residual dust. It is recommended to use it in a filter bag placed in a high-flow area, without excessive agitation.

The recommended dosage is 85 ml for 200 L of saltwater or 400 L of freshwater. The media is generally effective for 4 to 5 days in cases of high phosphate levels. Continuous use in small quantities is preferable to occasional treatments with a high dose.

Monitoring and Replacement

After a few days of use, phosphate or silicate concentrations should be tested. If the values do not drop to around 0.02 mg/L, the media should be replaced. As long as concentrations remain stable, PhosGuard is not considered exhausted.

Reef Safety and Compatibility

Under normal reef conditions, no detectable release of soluble aluminum is observed. Temporary closures of corals may be linked to a too rapid drop in phosphate, not to media toxicity. It is therefore recommended to avoid overdosing.
