AquaClear 50/200 Activated Carbon — Replacement 3-Pack 210 g HOB Filter - Fluval

The AquaClear 50/200 Activated Carbon (3-pack) is the replacement chemical filter media for Fluval's AquaClear 50/200 hang-on-back power filter. It improves water clarity by adsorbing dissolved impurities.

Filtration Role

Activated carbon provides chemical filtration: through adsorption it removes odors, discoloration and dissolved impurities for clear water. Fluval notes that rinsing only removes surface debris, not impurities already adsorbed - so the carbon must be replaced regularly.

Compatibility

This carbon is designed specifically for the AquaClear 50/200 filter (aquariums 76-190 L / 20-50 US gal) and is safe for both freshwater and saltwater.

Maintenance and Replacement

Per Fluval's directions, replace the activated carbon monthly - more often in a heavily stocked tank. Never replace all media at once: stagger replacements to preserve the beneficial bacteria colony.

Use in Marine Aquariums

AquaClear carbon is saltwater-safe. In a reef setup it is mainly used occasionally, to polish the water or remove dissolved impurities.

Frequently Asked Questions

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

Fluval recommends replacing the carbon monthly. Rinsing does not remove impurities that are already adsorbed, so regular replacement matters.

Is AquaClear carbon safe for saltwater?

Yes. Fluval states it improves water clarity in both freshwater and saltwater aquariums.

Can I just rinse the carbon instead of replacing it?

No. Per Fluval, rinsing only removes surface particles; adsorbed impurities remain in the carbon, which must be replaced.
