Product Information
Full details
Seachem SeaGel is designed for advanced aquarium hobbyists managing reef, marine, or non-phosphate buffered freshwater setups. It offers a powerful 50/50 blend of MatrixCarbon and PhosGuard to simultaneously remove organic waste, silicates, and phosphates for crystal-clear water. While highly effective at chemical filtration, users must exercise caution as the product generates heat and reacts when initially wetted, necessitating a thorough rinse before deployment.

Extended Product Information
FAQs
Can I use SeaGel in a planted freshwater aquarium?
Yes, but ensure your tank does not use phosphate-based buffering agents, as SeaGel will remove them.
How often should I replace the media?
It is recommended to replace the media every 3 to 4 months for optimal chemical filtration.
Why does the product fizz and heat up when wet?
This is an expected exothermic reaction when the dry media is initially exposed to water.
Does this product affect my tank's pH?
No, the MatrixCarbon component is designed to be pH-neutral.
Is it safe for reef tanks?
Yes, SeaGel is specifically engineered to be safe and highly effective for marine and reef environments.
Do I need to wash the media before putting it in my tank?
Yes, always rinse the media in a filter bag under running water until the runoff is clear.
Troubleshooting
Water appears cloudy after adding the product
This is usually caused by residual dust. Ensure you rinse the filter bag thoroughly until the water runs clear before installation.
Product gets hot when I rinse it
This is a normal exothermic reaction caused by the product being wetted for the first time; continue rinsing until the reaction subsides.
Phosphate levels remain high despite usage
Check if your filter bag is clogged or if the media has reached its saturation point; replace the media if it has been in use for more than 4 months.
Pros and Cons
Pros
- Simultaneous removal of both organic impurities and phosphates
- Spherical bead shape maximizes water contact for better efficiency
- Does not negatively impact water pH levels
- Provides long-lasting filtration (up to 4 months)
Cons
- Requires careful handling and thorough rinsing before use
- Not suitable for freshwater tanks that use phosphate-based buffering systems
- Generates heat during initial wetting process
Setup, Compatibility & Care
To prepare Seachem SeaGel, always place the required amount into a filter bag. Before placing it into your filtration system, rinse the bag thoroughly under tap water to remove any fine dust. Be prepared for a brief fizzing reaction and a release of heat upon contact with water; this is a normal chemical property of the product. Ensure your aquarium does not utilize phosphate buffers, as this product will actively remove them, rendering those buffers ineffective. Replace the media every 3 to 4 months to ensure continued absorption efficiency.
