Its advanced, highly porous, bead-shaped media maximizes surface area for superior adsorption capacity. This means clearer water, healthier fish, and a more beautiful aquarium. Unlike generic treatments, PhosGuard's formulation is designed to outperform, ensuring your aquatic environment remains pristine. It is imported from authorized US retailers, guaranteeing an authentic product for discerning aquarists. **Ideal For Indian Aquarists & Specific Tank Needs** — This product is ideal for aquarists in India facing challenges with tap water impurities or seeking to maintain optimal conditions for sensitive marine or freshwater species. It is particularly beneficial for planted freshwater tanks where silicate can inhibit plant growth, and for marine tanks where phosphate can fuel nuisance algae. However, it is not recommended for use with phosphate-based buffers in freshwater aquariums. If you have a phosphate-buffered freshwater system, consider alternative Seachem products designed for that specific application. ## How to use 1. Before use, rinse the Seachem PhosGuard media thoroughly with freshwater. This step is important as it may generate heat on initial contact with water and removes any fine dust. — Rinse Media 2. Place the rinsed media into a filter bag. Position the bag in a high-flow area of your canister filter, media chamber, or trickle filter to ensure maximum water contact. — Place in Filter 3. Use 85 mL (approximately 1/3 cup) for every 200 L (50 US gallons) of saltwater, or 85 mL for every 400 L (100 US gallons) of freshwater. Adjust based on your tank's specific phosphate and silicate levels. — Determine Dosage 4. Monitor your aquarium's phosphate and silicate levels regularly. Replace the media when levels begin to rise again, typically every 1-3 months, to maintain optimal water quality. — Monitor and Replace ## Product details | Field | Value | |---|---| | Active Ingredients | Proprietary porous, bead-shaped resin | | Phosphate Removal | High capacity | | Silicate Removal | High capacity | | Allergens | None stated | | Free From | Phosphate-buffered freshwater systems (not recommended) | | Recommended Use | Place rinsed media in a filter bag within a high-flow area of canister filters, media chambers, or trickle filters. | | Dosing - Saltwater | 85 mL (1/3 cup) per 200 L (50 US gallons) | | Dosing - Freshwater | 85 mL (1/3 cup) per 400 L (100 US gallons) | | Initial Contact | May generate heat; pre-wet with double volume freshwater, then rinse. | | Cost per use | 400 ml total treats up to 240 US gallons (908 L) at max freshwater dose: ₹29.72 per US gallon | | Shelf life after opening | Does Not Expire (when stored properly) | | Reapplication math | Replace when phosphate/silicate levels begin to rise again, typically every 1-3 months depending on tank load. | | Contraindications | Not recommended for phosphate-based buffers in freshwater aquariums. | | Allergens / common irritants | None stated | | Brand | Seachem | | Product Name | PhosGuard | | Model Number | 185 | | Item Form | Bead-shaped media | | Color | White | | Material | Plastic bag, proprietary media | | Total Volume | 400 ml (13.5 US fl oz) | | Individual Bag Volume | 100 ml (3.38 US fl oz) | | Pack Quantity | 4 bags | | Item Weight | 0.24 kg (0.53 lb) | | Package Weight | 0.4 kg (0.88 lb) | | Item Dimensions | 1.9 cm x 13.4 cm x 18.9 cm (0.75 in x 5.28 in x 7.44 in) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Attributes - **Item form:** Liquid ## Frequently asked questions ### How to buy an original Seachem PhosGuard in India?

Always pre-wet and rinse the media before use. ### What is the benefit of Seachem PhosGuard's bead-shaped media? The bead-shaped, highly porous media maximizes surface area for high capacity phosphate and silicate absorption. This design also ensures optimal water flow through your filter, preventing clumping and enhancing overall filtration efficiency for clearer, healthier aquarium water. ### Is Seachem PhosGuard suitable for planted freshwater tanks in India? Seachem PhosGuard effectively removes silicate, which can inhibit plant growth. It is suitable for planted freshwater tanks, helping to maintain clear water and support plant health. However, it is not recommended for use with phosphate-based buffers in freshwater aquariums. ### How often should I replace Seachem PhosGuard? Replace Seachem PhosGuard when phosphate and silicate levels begin to rise again. This typically occurs every 1 to 3 months, depending on your aquarium's bioload and feeding habits. Regular testing will help determine the optimal replacement schedule for your tank. ### What are the side effects of Seachem PhosGuard? Seachem PhosGuard has no direct side effects on fish or invertebrates when used as directed. However, it is not recommended for phosphate-based buffers in freshwater aquariums.
