Seachem PhosBond directions and guidelines

Product Description

Seachem PhosBond - 100ml

Seachem PhosBond is a premium phosphate and silicate removal media designed for both freshwater and saltwater aquariums. Seachem describes PhosBond as a hybrid filtration media that combines the phosphate removal characteristics of aluminum oxide and granular ferric oxide into a single material. This combination is intended to deliver fast phosphate and silicate reduction while also maintaining strong physical integrity, helping the media resist breakdown under normal mechanical stress. Its high porosity and large surface area further support substantial binding capacity for ongoing nutrient control.

Why Choose Seachem PhosBond

For aquarists working to control phosphate and silicate without relying on oversized amounts of media, Seachem PhosBond offers a focused approach built around fast adsorption and solid mechanical durability. It is especially useful in reef systems where phosphate management is critical for coral health and nuisance algae control, but it can also be applied in freshwater aquariums where silicate and phosphate reduction are needed. Because Seachem recommends continuous use of smaller quantities rather than intermittent heavy treatment, PhosBond fits well into a more controlled long-term nutrient management strategy.

Directions for Seachem PhosBond

Rinse the media before use
Place it where water flow is strong through the media but not so strong that the media tumbles against itself
Use in a canister filter, media chamber, box filter, or any high-flow area of a trickle filter
Seachem recommends using a filter bag such as The Bag
Use 60 mL for every 200 L (50 US gallons) of saltwater or 400 L (100 US gallons) of freshwater
Leave the product in place for 4 days and then test phosphate or silicate concentration
If the level has not dropped to around 0.02 mg/L, replace the media
If the level has dropped appropriately, leave the media in place until concentrations begin to rise again
Continuous use of smaller quantities is preferred over intermittent use of larger quantities
Do not use in a tumbling media reactor because Seachem advises that tumbling can cause this media to produce dust
