TMC Vecton V2 UV Steriliser Range Review

UK based company TMC bring us a range of UV Sterilisers by the brand name of Vecton. Their latest range is the V2 which we believe stands for version 2 and the main difference in this range compared to the original units is the inlet and outlet are now on opposite sides of the unit allowing for a better and neater plumbing solution, it is also made from hardwearing translucent polycarbonate and includes a UV shield to help prevent direct viewing of the UV lamp. The simple to use inlet and outlet pipes allow simple installation and the four stage hosetail are held in place by screw-on collars, making maintenance simple and easy.


The current V2 range comes in 5 variants designed for different sized aquariums:

Please take a look at our guide on whether you think you should use a UV steriliser or not for your aquarium as they are not always essential. However if you are considering buying a separate unit for this then the TMC Vecton V2 range is highly recommended.

Another consideration to take in to account is replacing the tube every 12 months (as recommended by TMC) although this would be the case with any UV steriliser so we cannot hold this against them, this is more of a negative about using this as a solution rather than specifically the TMC version.


The V2 Vecton range does cover most home aquarium requirements and if you require bigger then it could be worth looking at a pond UV steriliser.

Overall we would recommend these units as representing good value for money from a well respected, quality company. You are sure to know the unit will last and not fail on you.
