Companies like Eheim, Fluval, ''et al.'' were producing high quality canisters in many sizes in Europe, with some being imported to the US. In the US, the "workhorse" power filter was the Dynaflo 150, a HOB, magnetically-driven filter which could be run as a "full flow" filter using two plastic plates to hold the media, or as a "disposable cartridge" filter. |
MarineLand entered the US market around this time with their AF-1 and AF-2 filters, which were upclass parallels to the Dynaflo 150 in the first case, and a double-size unit in the latter. They were quieter and more subtle, in the European tradition. | MarineLand entered the US market around this time with their AF-1 and AF-2 filters, which were upclass parallels to the Dynaflo 150 in the first case, and a double-size unit in the latter.
