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 both 04 and 06 FX5/6 Fluval external filter models.
