    uv light
  • 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.
  • Radiation present in sunlight, fluorescent light, and to some degree incandescent light. UV light degrades photographs, papers, plastics, adhesives, fabrics and colorants.
  • 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.
  • A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
  • remove by passing through a filter; "filter out the impurities"
  • A porous device for removing impurities or solid particles from a liquid or gas passed through it
  • device that removes something from whatever passes through it
  • an electrical device that alters the frequency spectrum of signals passing through it
  • A device for suppressing electrical or sound waves of frequencies not required
  • Hold back or dam up (flowing water or another liquid) to form a small lake
  • (of flowing water or other liquids) Form such a lake
  • A pond is a body of standing water, either natural or man-made, that is usually smaller than a lake.
  • 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).
  • a small lake; "the pond was too small for sailing"

Sunterra 300207 Pond UV Bio-Filter 2000 Gallons, Black
Sunterra 300207 Pond UV Bio-Filter 2000 Gallons, Black
A contained body of water is subject to conditions such as dirt, insects, algae and decomposed vegetation that affect the water clarity and health. A filtration system is needed to balance the ponds ecosystem. This filtration system must match both the power of the pump and the volume of the water garden. All Sunterra filters use mechanical and biological filtration. The mechanical filtration process uses foam filters to trap debris. While the biological filtration uses biological ball (bio balls), that have large surface areas used to nurture beneficial bacteria. This beneficial bacteria converts harmful pathogens into useful nitrates. Both types of filtration work together to provide a clearer and healthier pond. The Sunterra Bio-filters utilize a dual filtration system consisting of both mechanical (foam filters) and biological (bio balls) processes. UV Pond filters are for ultimate filtration performance. They combine the same features of mechanical and biological processes of other Sunterra filters and have the added benefit of ultra-violet light filtration. UV radiation eliminates the algea that survive the normal flitration process, creating a clearer and healthier water garden. This particular UV Bio Filter cleans ponds up to 2000 gallons. It is recommended for use with pumps that are capable of pumping between 1,250 to 2,000 gallons of water.

Ok you know the opening theme music for the movie 2001: A Space Odyssey? That's how I feel! I finally got the lens I've been wanting for so long. Canon 100-400mm f4.5-5.6 L.... Yeah baby! And... I got a Canon 1.4xII extender to go to way out there to 560mm. And... a Sigma 10-20mm f4-5..6 wide angle lens that I didn't take out of the box until just a few minutes ago. But I'll try it out tomorrow. They came with lens hoods and the cutest little cases, although now I need a big one to store all my gear. I also got a really good quality UV filter. I look like I'm carrying a cannon (unintentional but humorous pun). Of course I had to try it out so I went to Brazos Bend SP and did some hiking. I just used Auto with manual focus and took my tripod, but used the monopod part of it most of the time (mine converts). It's definitely heavier, but not unmanageable. I just need to practice with it a bit because it definitely reacts to light differently than the 70-300mm. So... I feel like I'm embarking on a completely new journey with my photography. I'm just so excited!!!! :) BTW... SOOC with a crop!
Spent a lot of time outside yesterday, with dad, trying to get the uv lights on the pond filter to work. Not sure if the bulbs are actually fried or not. Must buy more, tomorrow.
