Frequently asked questions

How often should I replace the AquaClear 50/200 activated carbon?

Fluval recommends monthly replacement of activated carbon. Adsorption capacity drops gradually after that period. More frequent replacement may be needed after a medication treatment.

Can this activated carbon be used in a reef aquarium?

Yes for a reef in passive dosing, but avoid or remove it if you actively dose trace elements, iodine, or vitamins: the carbon adsorbs them and can create deficiencies. Many reefkeepers swap the carbon for Purigen or BioMax in the center tray.

Should I rinse the activated carbon before use?

Yes, rinse under tap water for 30 to 60 seconds to remove carbon dust before placing it in the filter. This prevents cloudy water during the first hours of use.
