The SunSun CT-201 is a single-outlet aquarium air pump for keepers who need to control how much air enters the tank. It is built to replace CO2 in the water with oxygen from the air, which supports fish and plants and helps keep the water's pH stable.
Why it matters
- Stepless power control: the power can be adjusted continuously, so the air output can be set to match the tank.
- Low power draw: the pump is rated at 4W, and the redesigned coil with more windings is intended to reduce current consumption.
- Durable components: the membrane is made from an elastic material, and the shaft connecting the electromagnet to the membrane is made from a titanium alloy that is heat resistant and lighter than conventional parts.
- Low vibration: soft rubber feet keep vibration from passing into the surface the pump stands on, and a rubber hanger provides a similar function when mounted.

What it works with
The CT-201 is listed in the exotic aquatic category under filtration, pumps and aeration, so it is intended for aquarium aeration. With a 4W rating and 1.5 L/min output, it is a compact unit for a single air line in a freshwater or aquatic setup. Check the output against the tank volume and the number of air-driven accessories you plan to run.
