Description

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.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $16 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Seachem products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
