Seachem SeaGel is a premium dual-action filtration media designed for aquarium hobbyists looking to maintain pristine water quality in marine, reef, and non-buffered freshwater environments. By combining MatrixCarbon and PhosGuard into a single, bead-shaped formula, it effectively clears water coloration, absorbs organic impurities, and removes phosphates, silicates, and toxic metals. While it provides exceptional water clarity, it is important to note that it should not be used in freshwater tanks that rely on phosphate buffers, as the media will actively strip these buffers from the water.

You can use it in a planted tank as long as you are not using phosphate-based buffers for pH or fertilization.
For most aquariums, replace the SeaGel every 3 to 4 months to ensure continued absorption efficiency.
Yes, always rinse the beads under tap water to remove fine dust particles that can cause cloudy water.
While it is primarily focused on impurities, carbon can remove some trace elements, so it is recommended to replenish minerals as part of your normal maintenance routine.
Yes, SeaGel is specifically designed to be safe for reef environments and helps maintain the water purity that corals require.
This is likely carbon dust. Remove the media bag and rinse it under running water more thoroughly until the water runs clear.
Ensure the media is placed in an area of high water flow. If flow is bypassed, the media cannot effectively process the water.
To set up Seachem SeaGel, simply add the desired volume to a mesh media bag and rinse until the water runs clear. It is compatible with most canister and sump filter systems. When using, monitor phosphate levels regularly with a test kit to determine when the media is exhausted, as the beads will not change color to indicate expiration. For optimal performance, replace the media every 3 to 4 months. Do not use in freshwater aquariums that utilize phosphate buffering, as the media will negate the buffering effect and potentially cause pH instability.
