Aquael Fan 3 Plus Internal Aquarium Filter review

FAN 3 PLUS is the largest of the five current US FAN sizes. Aquael assigns it item number 120622 and prints 35–65 US gallons / 150–250 liters, an 8.2 × 9.4 × 27.6 cm body (3.2 × 3.7 × 10.9 inches), 10 W and a listed efficiency of 180 US gallons per hour paired with 700 L/h. Those details set it apart from FAN 2, which is shorter and carries a 25–35-gallon label. They do not establish a stocking, fish-count or waste-load ceiling.

Choosing the largest FAN size

At 40 gallons, the current FAN 3 interval is the only FAN band above 35; at exactly 35, the FAN 2 and FAN 3 labels touch. That offers a useful catalogue comparison, not a biological prescription. Pump flow and aquarium gallons are both maker-published figures, but neither specifies the movement a particular species needs or what happens as the sponge loads. The current table gives one efficiency number rather than a full flow curve. The family page says output is adjustable and the outlet can turn, which aids setup, but its minimum current-item flow remains unknown.

FAN 3's 10.9-inch height is a meaningful inside-the-tank clearance check, as are the width and depth for a chosen panel. An internal filter avoids a canister below the aquarium and the external hose path, but the 3 Plus unit itself is comparatively tall and has to fit in the display. Consider the area around the outlet and whether you can lift the pump out without shifting the hardscape. A large flow number should not be treated as an assurance that the result will be quiet or suitable for every aquarium occupant.

Mounting and maintenance

Aquael describes the FAN family as using an adjustable hanger, four suction cups, adjustable pump output, a swivel outlet and aeration. In the shared English manual, the filter is placed on a holder inside the tank; an air tube can connect to the aeration socket and regulator. The manual recommends at least 3 cm submergence for best effect and advises allowing for evaporation. It also instructs owners to unplug before service, remove the sponge cartridge, and clean the rotor monthly. These are useful maintenance points, but the manual's generic technical table is not a current US item-number crosswalk.

That distinction matters here. The manual's FAN 3 row lists 12 W, 120–700 L/h and a 150–200-liter volume range. Aquael's current US row for item 120622 lists 10 W, 180 US gal/h / 700 L/h and 150–250 liters (35–65 US gallons). Those power and capacity differences could reflect product version or source age; the available documents do not identify a bridge between manual and current US article code. I retain the exact US table for this current item and do not import the older 12-W value, its 200-L ceiling or its generic flow range as item-specific facts.

Media capacity and what remains open

The FAN Plus design uses a sponge cartridge, with manufacturer catalogues listing replacements by size. The current item data does not give a volume in liters for the FAN 3 sponge. That makes the product a poor match for a shopper who requires a stated minimum basket volume; it cannot pass a numeric minimum on the assumption that the largest body must hold enough media. Aquael also does not publish a high-bioload rating or fish-count target for the current US size, so the 65-gallon end remains a screening label rather than a load guarantee.

The US source gives power in watts but not a current item-120622 voltage or frequency. The gallery photograph associated with FAN 3 shows older code 102370 and a 230 V / 50 Hz / 12 W label. Its body is useful for identifying FAN 3 Plus, but the visible electrical line conflicts with the current US table and does not verify this SKU's nameplate or retail box. Before buying, check that the seller supplies item 120622, verify its electrical marking, and confirm what sponge and accessories are actually included.
