MatrixCarbon is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. MatrixCarbon has a very low ash content as indicated by its minimal impact on pH. KEY FEATURES: High efficiency spherical carbon Very little impact on pH due to low ash content Lowest leachable phosphate level on market High removal capacity; large surface area DIRECTIONS: 250mL will easily treat 400L (100 US gallons) for several months. Use in a filter bag. Rinse before use. For best results, MatrixCarbon should be placed so as to maximize the flow of water through it. It may be used in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter.Best Before Guarantee: 30/05/2026

PhosNet is a granular ferric oxide (GFO) with high porosity, high surface area and high binding capacity. It will rapidly remove phosphates and silicates from both freshwater and saltwater and will not release them back into the aquarium. KEY FEATURES: Rapidly removes phosphate and silicate Synthetic granular ferric oxide (GFO) Less dust and thus is easier to use than most competing GFO products DIRECTIONS: For best results, PhosNet 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. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag such as The Bag is recommended. Use 50g (1/2 cup) for every 200L (50 US gallons) saltwater or 400L (100 US gallons) freshwater.Best Before Guarantee: 30/06/2025
