Rinse the new cartridge briefly under tap water before fitting to clear carbon dust.\u003c\/p\u003e\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003ch4\u003eCan I rinse and reuse Zeo-Carb?\u003c\/h4\u003e\n\u003cp\u003eNo. Once the carbon and zeolite are saturated they stop adsorbing and can release what they've captured back into the water — replace rather than rinse and reuse.\u003c\/p\u003e\n\u003ch4\u003eDoes this replace regular water changes?\u003c\/h4\u003e\n\u003cp\u003eNo. Zeo-Carb helps manage ammonia spikes and water clarity between changes, but it isn't a substitute for routine partial water changes.\u003c\/p\u003e\n\u003ch4\u003eWill it remove medication from the tank?\u003c\/h4\u003e\n\u003cp\u003eYes — like any activated carbon, it will pull aquarium medications out of the water, so remove it before dosing treatments and only refit it once the course is finished.\u003c\/p\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eCovered by Fluval's standard consumer guarantee in addition to your rights under Australian Consumer Law.
