The need to install an ultraviolet lamp for an aquarium still causes many breeders questions. There are both revealed advantages of such a device, as well as disadvantages.
Benefit from an ultraviolet lamp for an aquarium
The main advantage of such equipment is that ultraviolet has a harmful effect on many dangerous bacteria and viruses, which means that the fish in the aquarium, where there is such a lamp, will be less likely to become infected and live a long time. In addition, such a lamp is able to purify water from the formation of turbidity and keep the liquid in a suitable condition for the comfortable living of the aquarium inhabitants, that is, this is another additional stage of water purification. That is why ultraviolet lamps are often sold together with filters for the aquarium.
In addition, some species of fish living in the upper layers of water, as well as plants, are useful to receive small doses of ultraviolet radiation, it has a beneficial effect on their development and can accelerate growth.
Disadvantages of the ultraviolet lamp
The downside of such an arrangement for an aquarium is that it is not capable of completely replacing any of the other adaptations necessary for normal vital activity of fish. Such a lamp will not save you from installing filters and water purifiers, as well as periodically replacing some of it. The ultraviolet lamp can not be used instead of the illuminating devices for the aquarium, in addition, if the water already has a strong turbidity , the lamp will not cope with it, and the water will have to be changed. In large aquariums, an ultra-violet lamp of a small size will not be effective at all, since its radiation will not be strong enough to penetrate the water column. In addition, the device is quite expensive, and the effect from it is not too much noticeable. That's why many aquarists consider the purchase of an ultraviolet lamp a waste of money.
