TMC Nano Water Change Barrel Pump (Reef Pump Compact 350)

  • Water is fed through the base of the pump and small feet on the pump allow it to stand comfortably on flat surfaces
  • Quiet running
  • Variable speed control

Make maintaining your aquarium easier with the TMC Nano 350 water pump. Ideal for both removing water from your aquarium and then adding it back in once your have carried out your clean. The pump comes with a controller and has an adjustable flow so no matter the height of your aquarium you can have a controllable flow of water.

Traditionally water pumps have always sat horizontally but the team behind the TMC Reef Compact Pump has flipped this idea on its head, quite literally! The small space-saving compact pump sits vertically and draws water in from the base. The initial problem with this is the restricted flow especially if debris builds up around the base but thanks to the pump's rubber feet it will sit just high enough to avoid this problem and the rubber feet help reduce movement and noise levels. The TMC Reef Compact is ideal for any aquarium owner who is tight on space.

  • UNIQUE ULTRA-COMPACT SPACE-SAVING DESIGN enabling easy installation in small aquariums and sumps where space is a premium
  • ABILITY TO WORK IN LOW-LEVEL WATER, perfect to help with water changes

  • Feature a UNIQUE SELF-COOLING SYSTEM that channels water around the motor to ensure optimum operating temperatures

  • Low voltage

  • VARIABLE SPEED CONTROL with up to 10 different speed settings, offering precise adjustment of water flow for optimum performance


  • Integrated 10 minute feed timer to allow easy feeding

  • SOFT START FEATURE to increase impeller life
