Frequently asked questions

Can the Eheim Classic 150 be used on a marine or reef aquarium?

Yes — the canister and seals handle saltwater. On reef tanks it's mostly used as an auxiliary filter (activated carbon, resin) rather than the main filtration (a sump is still preferred).

How often should the Classic 150 be serviced?

Clean the pads every 4-8 weeks, swap activated carbon every 3-4 weeks, rinse biological media in tank water (never in chlorinated tap water) every 6-12 months.

What's the max aquarium size for the Classic 150?

150 L (40 US gal) for main filtration. Can be used on a larger tank as a dedicated auxiliary filter for a specific media.
