Does UV light purify water?
Ultraviolet purificationitself is not enough to purify water down to drinking water purposes. This is because the UV radiation is only effective for treating bacteria and viruses. UV light does not work to eliminate contaminants such as chlorine, heavy metals and VOC’s (Volatile Organic Compounds).
Can UV light harm goldfish?
Unlike some other fish, goldfish don't require ultraviolet light, and may not need a heat light because they live in cool water. However, light still plays an important role in goldfish health, and without a daily and consistent light cycle, your goldfish may become ill.
Can UV light get rid of algae?
Will UV Sterilizer Kill Algae? Yes, UV steriliser kills algae by bombarding it with ultraviolet radiation in the same manner that it kills other microbes, and it kills free-floating algae by limiting reproduction. Because algae add so much to the turbidity of your water, this improves the clarity of your tank.
What does UV light do to algae?
UV lights work when water from your pond is pumped through their light path. The single-celled, free-flowing algae within your pond water is then exposed to these high levels of ultraviolet light. This light destroys their DNA and kills them.

Should I run my UV sterilizer all the time?
An aquarium UV steriliser should be switched on and running for 24 hours per day, every day. Exceptions would be setting the tank up before there are any fish in it, adding beneficial bacteria to the water, as UV light kills bacteria, or if you are using a medication that stipulates that UVs should be turned off.

Does UV light cause algae in fish tank?
No, UV light is not the cause of algae in fish tanks. Fish tanks are algae producers whether they contain UV lights or not. Given that fish use lots of oxygen, any biological material (organic waste plus dead fish) in the water means more growth for algae.
How long should a UV light be on in an aquarium?
The amount of time that a UV light should be on in an aquarium depends on the type of fish you have. Some fish are more sensitive to UVA than others, so it is important to test your water’s PH and ammonia levels with a test kit before starting up your UV light.

What is the best way to kill algae in a pond?
UV sterilizers are most helpful in multiple tank systems that share a common filter. In ponds, UV sterilizers are one of the best ways to control free-floating algae, allowing the pond owner to see and enjoy the fish. The UV sterilizer will also kill free-floating bacteria in the pond water.
Does UV light kill algae?
Furthermore, does a UV light kill parasites? Unlike the UV sterilizer, the UV Clarifier does not kill the green water algae; instead it causes the algae particles to clump as the water passes though the UV light, enabling the filter mat to catch the small green water algae particles. It also does not kill parasites.
What does ultraviolet light do to a pond?

What is bluegreen algae?
The bluegreen algae blooms in and around Florida coastal areas has caused significant economic losses recently. In the coastal waters it kills fish and marine animals. In local rivers and canals it caused fish dieoffs and considerable mess cleanup was required. This stuff is properly called cyanobacteria and is not a plant. It clumps and forms thick mats on top of still waters and piles up on beaches when it dies, it uses up most of the oxygen in the water, in decomp. it reeks. The dead bacteria are toxic if consumed or breathed as when ejected by wave acttion into the air. Presently there is
Why is blue green algae not blue green?
Blue green algae could not remain as blue green algae more , because they were regarded as CYANOBACTERIA by ICBN (international code of nomenclature for bacteria) in 1978.
What is the name of the bacteria that produce oxygen?
Cyanobacteria, or blue green algae or even cyanophyta are bacteria instead of algae and are referred to algae due to their aquatic blooms looking similar to algae mats. This bacterium is a prokaryote conducting photosynthesis and actually produces oxygen. In fact in the earlier part of Earth's biological history, cyanobacteria in the form of stromatolites, were one of the major contributors of oxygenating the atmosphere.
How does blue light affect algae growth?
We hypothesized that the sample under blue light would grow faster than the sample in the red light because blue light occurs at a higher frequency on the visible light spectrum . We placed one falcon tube under each of the colors of light, and the control group was placed under the white light and measured the growth each week using a dissolved oxygen probe. By comparing the data using Excel we were able to determine which group had a bigger growth rate. Our results show that algae grows the best under white light and more in blue light than red light. Therefore, our hypothesis is partially supported because the growth rate was higher under the blue light in comparison to the red group; however, the algae under the control condition experienced the most growth. The results of this experiment are useful to biofuel producers because they could use white light to increase the growth rate of algae, which in turn produces more biofuel.
How does light feed algae?

However, once it is gone, it will be gone for good with an ultraviolet pool system on duty.
