Boyd Chemi-Pure Green Filter Media

Boyd Chemi-Pure Green is a freshwater-specific formulation of the classic Chemi-Pure chemistry, designed for planted aquariums where you want chemical filtration without stripping out the fertilizers your plants need. Standard activated carbon pulls trace elements and nutrients from the water column right alongside the organics you actually want removed — a problem in any planted tank running a fertilizer program. Chemi-Pure Green uses a selective resin that removes organics, tannins, and odor-causing compounds while leaving macro and micro nutrients available for your plants.
