Seachem SeaGel Dual Filtration Media for Marine & Freshwater Aquariums, 1L

Seachem SeaGel 1L is a powerful blend of two premium filtration media—MatrixCarbon and PhosGuard. Designed for both saltwater and freshwater aquariums, Seachem SeaGel effectively removes organic waste, phosphate, and silicate. It keeps aquarium water crystal clear and chemically balanced.

MatrixCarbon in SeaGel is a high-efficiency activated carbon. It removes color, odors, and harmful organic compounds without releasing phosphates. PhosGuard, on the other hand, eliminates phosphates and silicates that can cause algae growth and water cloudiness.

This combination makes SeaGel ideal for reef tanks and marine systems, where maintaining low phosphate levels is critical. It also supports freshwater tanks by improving clarity and reducing organics. The media works fast and remains effective longer than standard carbon or phosphate removers.

Seachem SeaGel is easy to use. Place it in a filter bag and add it to any filtration system—canister filters, sumps, or internal filters. It requires no rinsing and does not affect pH. Use SeaGel regularly for a clean, healthy environment for fish, plants, and corals.

Aquarists trust Seachem SeaGel to keep water clear and nutrient-free. Its dual-action formula saves time and improves water quality in all aquarium types.
