Fluval ClearMax is a science grade resin designed to adsorb phosphate, nitrite and nitrate.
Reducing the levels of these nutrients not only leaves a clean, healthy tank, it also lowers the possibility of algae problems.
Clearmax 300g comes with 3 x 100g bags that can be popped in to the filter easily. As the water passes through, the resin will cleanse it of any unwanted nutrients and odours - leaving a healthy, fresh tank and happy, healthy fish and plants.
Clearmax treats 300L (80 US gal) and is suitable for both fresh and saltwater aquariums.
It is compatible with all 04/05/06 and FX5/6 Fluval external filter models.
