CIRCULATOR 1000

The Aquael Circulator 1000 is a submersible impeller pump for aquarists running 150–250 L tanks who need strong circulation, a sump pump or an air source for aeration. Its fully sealed body lets it operate outside the water, which gives it enough lift for sump and external setups.

Why it matters

• The motor is energy-efficient and rated at 11 W, while the sealed gaskets around the impeller chamber are designed to minimise losses in output.
• A knob on the outlet nozzle gives a smooth flow adjustment, so the current can be matched to the tank without changing the pump.
• The outlet direction can be turned through 120°, which helps aim the stream at the glass, plants or the filter intake.
• The ceramic impeller shaft is intended to keep operation quiet and durable, according to the manufacturer.

What it works with

The pump suits freshwater and marine tanks where the stated volume range applies and it can be used as a circulation pump in sumps, as an aerator at depth, or as the drive unit for a mechanical, biological, chemical or UV-C filter built from the wide range of accessories available for it. Pair it with a tank within the 150–250 L range to match the rated flow to the setup.
