Has anyone built their own UV filter? If so, I would like to pick your brain concerning the pros and cons of doing it yourself. We have a 12,000+ pond and before I break down and buy one would like to explore the possibility of making our own.
Thanks,

UV Filters
If you havn't already, check out Wikipedia on the hazards of UV light. I use two UV's for my 2000 gal. koi pond. Pricey, but worth it. I replace the lamps after two seasons of use. I can sure see the appeal of saving the costs but I question the hazards of exposure to stray UV light. 12,000 gallons sounds like a dream pond. Good luck!
