the last ranch I worked for we used UV systems. I maintained all the water tanks for the cattle, total of 6 tanks, 4 10k gallon and 2 25k gallon. the 10k's had a bulb for each and the 25k's used 2 bulbs per. system sounded like a great idea when I signed the contract with the manufacturer. also had them install the units. takes 72 hours for the ozone generated to begin to filter the water. the ozone produced only has a 30 minute half-life. but that's all basic info, now the hate. 2 weeks go by, water smells really bad. I check the bulb housing to see that the bulb has burned out. no big deal since we had a few replacements. cotton gloves and rubbing alchol later and it's replaced. turn unit back on and smell that ozone is being produced again. 2 more weeks and the systems are broken in, now regular maintenance can begin. 1 month later and 2 more bulbs burn out, replaced 1 and ordered another, $149.95 a bulb. manufacturer comes out to see whats happening and they find 2 units have split pump diaphragms, another $90. jump 8 months forward... 5 bulbs, 3 housings, 1 filter, and 2 more diaphragms later. very unhappy, me, the foreman, and ranch owner are mad. manufacturer is hard to get hold of cause they filed a lawsuit against another company that using they patent for these units without permission. we ended our contract, ripped the units out, and were kind enough to ship the units back. not quite what you would expect for units that cost 2 grand each.

so if the leading manufacturer of UV water filtration systems can not produce a reliable unit for industrial use them they likely can't for home use.

I dont have a UV but i am planning to get one for my 540 and 135 , thats more then likely just that manufacturer , ive heard nothing but good results from UV systems
 
i have a tetra 5 watt pond U.V. ($20 on ebay)
i put it on my 240
water looks great but this besting about them is disease prevention
treating a big tank with meds will drain your fishkeeping budget :(

Your can't compare our (aquarist's) systems to the one you were caring for.
Ours do not produce ozone gas, I beleive I know the design your talking about and there were problems with materials and concentration limits. Ozone is very corrosive and there-fore difficult to work with, they just can't cut corners with materials with it.

UV's are well worth the cost, especially if your dealing with delicate fish or you don't watch your tanks closely.

Main problem with UV's is getting people to replace the bulbs on schedule.
