GERUI Submersible Water Feature Pump – 350L/H, 5W LED

This compact submersible pump is a neat little workhorse for anyone wanting to add movement and light to a fish tank, indoor water feature, or small garden fountain. Running at just 5 watts, it circulates up to 350 litres per hour and can push water to a height of 0.85 metres, making it well suited to tabletop fountains, aquariums, and modest hydroponic setups. An adjustable flow knob lets you dial in exactly the right pressure for your setup, and the copper wire motor keeps things impressively quiet — handy if it's destined for a living room or bedroom display.

What makes this pump a little more interesting than most at this size is the built-in LED lighting, which cycles through four colours — yellow, green, red, and blue — to give a water feature some genuine visual appeal after dark. The pump itself is tiny, measuring roughly 48 by 48 by 35 millimetres, so it tucks away easily behind rockwork or ornaments. Three suction cups on the base hold it securely in place, and it can be mounted either upright or on its side depending on your arrangement.

The motor is sealed with eco-friendly epoxy resin for reliable waterproofing, and the rotor is made from corrosion-resistant POM material, so it handles both fresh and salt water without issue. It comes with two nozzle sizes to vary the flow effect, and the whole unit pulls apart without tools when it needs a clean — a small but genuinely appreciated touch for anyone who's wrestled with fiddly pump maintenance before.
