The carbon polishes the water by pulling out odors, discoloration, and dissolved organics, while the zeolite actively removes toxic ammonia through ion exchange. It is the fast way to clear cloudy, smelly, or ammonia-stressed freshwater tanks.\u003c\/p\u003e\n\u003cp\u003eSetting up a new tank or restocking media?

Clear-Carb is carbon plus ClearMax, which targets phosphate and nitrogenous waste. Pick Zeo-Carb when ammonia is your concern.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow often do I replace it?\u003c\/strong\u003e\u003cbr\u003eEvery 3 to 4 weeks.
