The Vecton 600 UV V2 Steriliser Ticks All the Boxes.

  1. Ultraviolet sterilisers can be built in different ways in our opinion this design is correct. The water jacket made from white ABS reflects Uv unlike black plastics or stainless steel that adsorb Ultraviolet.
  2. The water jacket surrounding the UV light source in this unit has the correct diameter. Meaning the ultraviolet power does not become too weak over distance as in units with large jackets. Just like moving further from a fire the further away the less it can burn.
  3. The Vecton 600 UV Steriliser is easy to maintain and gives a long trouble-free service. We have units over 20 years old still going strong.

Uv Units Rated So Differently even with the same wattage, Why?

Uv can be applied at different rates depending upon what you are trying to control. Most Ultraviolet steriliser manufacturers state the highest litreage the unit can cope with. However, using terms such as “approximately” or “up to” can be deceptive. The high numbers that they throw about are true in some ways but misleading in others. The TMC Vecton 600 UV is 25 watts and will easily control water born algae, in aquariums of 600 litres and more. However, if you want to control protozoa i.e. whitespot then the highest litreage changes dramatically. It takes roughly 15 times more ultraviolet to deal with protozoa than water borne algae. Likewise, it takes around 100 times the amount of Uv to kill the bacteria that causes Dysentery than needed to control Ichthyophthirius multifilis (white spot).

How Much Uv Do I need?

Here at the Abyss we are firm believers in the values of ultra violet sterilization. We have used Uv on our own systems for more than 30 years and have highly recommended it for same time. We have found that the Vecton 600 UV Steriliser is able to control protozoa ,which is the number one reason we want install ultra violet sterilisers, for aquariums no more than 310 litres. If your aquarium is larger you can run 2 in series or we can supply larger more commercial units for extra-large tanks.

Flow rate for the Vecton 600 v2 UV Steriliser

We find that circa 3 – 3.5 times aquarium volume through the unit per hour works best.

TMC Vecton 600 UV fitment.

For sumps, the unit should always fit between the sump and fish tank and never just circulated around the sump. When using an external filter simply fit the UV if possible, on the output side but the input side is fine if it works out simpler.

The Uv can also be fitted using a pump in its own distinct circuit.
