Uv Light Pond Filter
- Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3eV to 124 eV.
- Electromagnetic radiation in the range of 300 to 400 nanometers. UV radiation is not visible and therefore “UV light” is a misnomer. UV radiation has been implicated in the degradation of photographs and papers.
- Radiation present in sunlight, fluorescent light, and to some degree incandescent light. UV light degrades photographs, papers, plastics, adhesives, fabrics and colorants.
- A porous device for removing impurities or solid particles from a liquid or gas passed through it
- A device for suppressing electrical or sound waves of frequencies not required
- A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
- device that removes something from whatever passes through it
- an electrical device that alters the frequency spectrum of signals passing through it
- Pond was a grunge band from Portland, Oregon. They formed in 1991 and broke up in 1998. They were signed to Sub Pop (first two albums) and the Work Records sub-label of Sony Records (last album).

- Hold back or dam up (flowing water or another liquid) to form a small lake

Purely Products PUVH2307 7-Watt UV-C Germicidal Ultraviolet Replacement Bulb
Purely UV-C Replacement Bulbs G23 BasePurely UV-C Replacement bulbs offer a much higher concentration of ultraviolet light than even the sun, making them highly effective as a cleaning and purifying agent for pond and aquarium pumps and clarifiers.What is UV and How Does it Work?UV light is germicidal - i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.What are the Beneficial uses of UV Light?Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance.How do Ultraviolet Water Purifiers Work?UV water purification units contain one or more germicidal ultraviolet lamps. The germicidal lamp is a short wave low pressure mercury vapor tube that produces ultraviolet wavelengths that are lethal to micro-organisms. This wavelength is in the region of maximum germicidal effectiveness and is highly lethal to virus, bacteria and mold spores. Therefore, the water or air that passes through the chamber is exposed to the germicidal UV light and the genetic material of the micro-organism is deactivated, which prevents them from reproducing and renders them harmless.Reference Tool for choosing the correct UV-C Replacement Bulb:Match your existing bulb to one of the bases.Match the wattage or length of your bulb. Some bulbs have a different length for the same wattage -- so be sure to match both watts and length.H-Series:The Purely UV L-Series carries the industry standard 2G11, G23 and GX23 base.The "H" is for the H-look with parallel glass connected by

A mystery: There really is no way for a fish to be able to get up into the top plant pond. Even an egg would have to travel through the skimmer filter, through the UV light, and up through three layers of filter padding in the waterfall. But there are several baby fish up in that pond, blissfully swimming around the plants. How'd they get up there?
