Seachem - Phosnet 150ml

Phosnet is a granular iron oxide (GFO) with high porosity, a large specific surface and a high binding capacity.

It quickly removes phosphates and silicates from both fresh and salt water and do not let them back into the aquarium. It shows a stronger bond than most competing products, and thus can reduce the amount of phosphates and silicates to very low levels.

Phosnetzawiera less ash, making it easier to use than most competing GFO products.
