QiQiWader Small Aquarium Filter — 5W, 110 GPH, 10–20 Gallon Tanks, 2 Modes

QiQiWader’s Small Aquarium Filter is designed for compact tanks where space matters but water quality still counts. This unit blends filtration with gentle water movement, helping maintain a clear, healthy-looking aquarium.

Key specifications include a compact footprint and efficient power usage: 5W energy draw, delivering up to 110 GPH, with a lift of up to 1.5 feet. The housing measures 1.8 inches long by 1.5 inches wide by 5.9 inches tall, so it tucks neatly in even densely stocked nano tanks.

Two modes to suit your aquarium setup

The filter ships with two interchangeable accessories—a spray bar for surface agitation and a separate oxygenation wave-making nozzle. Swap the part depending on whether you want a shimmering surface ripple or deeper water turnover.

• Spray bar delivers gentle, even laminar flow to encourage surface movement without overwhelming delicate plants or shrimp.
• Oxygenation nozzle creates a fine wave pattern that boosts dissolved oxygen where fish and beneficial bacteria thrive.

Filtration and biological balance in one compact unit

The filter uses a biochemical sponge to trap physical impurities, such as uneaten food and small debris, helping water stay visually clear. Paired with a small amount of biological filter media balls, it supports the growth of nitrifying bacteria, which contribute to a balanced aquarium environment.

• Biochemical sponge captures debris for clearer water at a glance.
• Biological media balls promote beneficial bacteria without taking up extra space.

Easy installation, simple maintenance

Strong suction cups secure the unit to the tank wall, and the filter component is removable for quick cleaning of the cotton. Replacement parts are straightforward, and maintenance is recommended every 2–5 weeks, depending on tank conditions.

• Secure attachment with powerful suction cups for reliable operation.
• Removable filter compartment facilitates easy cleaning of the filter cotton.
• Simple replacement parts keep downtime to a minimum; regular checks support long-term performance.
