How do I use Seachem PhosGuard in my aquarium?

Rinse Seachem PhosGuard thoroughly with freshwater before use. Place the 100 mL media in a filter bag and position it in a high-flow area of your filter, such as a canister filter or media chamber. For marine aquariums, use 85 mL for every 200 L (50 US gallons). For freshwater, use 85 mL for every 400 L (100 US gallons). Monitor phosphate and silicate levels; replace the media when levels start to rise again. It can be dried and reused until exhausted.

Can I use Seachem PhosGuard for both freshwater and saltwater aquariums?

Yes, Seachem PhosGuard is effective for both marine and freshwater aquariums. However, it is not recommended for phosphate-buffered freshwater systems. Always ensure you are using the correct dosage for your specific aquarium type to maintain optimal water parameters and prevent algae growth.

How long does Seachem PhosGuard last and can it be reused?

Seachem PhosGuard has a high capacity and can be reused. Once the media is exhausted and phosphate or silicate levels begin to climb, you can remove it, dry it thoroughly, and return it to service. Continuous use of smaller quantities is generally more effective than intermittent large doses. The product does not expire if kept dry.

What is the difference between Seachem PhosGuard and other phosphate removers?

PhosGuard is distinguished by its highly porous, bead-shaped media, which offers superior capacity and optimizes water flow compared to many competing granular or resin-based products. It rapidly removes phosphate and silicate without leaching contaminants back into the water, providing a more efficient and reliable solution for maintaining water quality in your aquarium.
