Product Information
Full details
Seachem PhosBond is an advanced filtration medium designed for both saltwater and freshwater aquarium hobbyists looking to effectively manage phosphate and silicate levels. By combining the strengths of aluminum oxide and granular ferric oxide, it offers a dual-action approach to water clarity and algae control. While it is highly efficient and physically robust, users should note that it is not a resin and requires careful placement in a high-flow area to achieve optimal chemical filtration results.

FAQs
Is PhosBond safe for reef tanks?
Yes, it is designed for both saltwater and freshwater, making it perfectly safe for reef environments.
How often should I test the water?
Test your phosphate and silicate levels 4 days after the initial application, and then periodically based on your tank's bioload.
Does it release silicates back into the water?
No, PhosBond does not leach phosphates or silicates back into the aquarium water.
Can I use it in a canister filter?
Yes, it is highly effective when placed in a canister filter tray where water is forced through the media.
How much should I use for a 400L freshwater tank?
Use 60ml of PhosBond for every 400L of freshwater.
Troubleshooting
Water appears cloudy after initial installation
The cloudiness is likely caused by fine dust that was not sufficiently rinsed; remove the bag and rinse thoroughly until the water runs clear.
Phosphate levels are not dropping
Ensure the bag is placed in a high-flow area; if the water is bypassing the bag, the media will not be effective.
Pros and Cons
Pros
- Simultaneous removal of phosphates and silicates
- Extremely durable material that resists mechanical stress
- Does not release compounds back into the water column
- Reusable until fully saturated
- Suitable for both fresh and saltwater environments
Cons
- Requires rinsing before initial use
- Must be placed in a high-flow area to be effective
- Requires periodic testing to monitor exhaustion levels
Setup, Compatibility & Care
To prepare PhosBond, always rinse the media under tap or RO/DI water to remove any fine dust produced during shipping. Place the rinsed media into a fine-mesh filter bag. Position the bag in an area of your filtration system where water flow is constant, such as an overflow chamber or a canister filter tray. PhosBond is compatible with all standard aquarium filtration setups. To care for the product, simply monitor your phosphate levels; when they begin to rise again, the product has reached its capacity. You may remove and dry the media for later use or replace it once entirely exhausted.
