UV sterilization thread

[TANGOMAN]

I'm of the belief they are of minimal value in a single system. Given the high cost of the unit and the ongoing cost of crucial bulb replacement. I think the money would be better spent on efficient skimmers etc. Though this does not erradicate pathogens, it will greatly improve water quality thus reducing one of many possible stress factors.
I had used one for many years on a single system and suffered losses far greater than I do at this time. Those losses were certainly not as a result of U.V. sterilization.
They were, I believe, as a result of limited experience, knowledge and guidance. These were times before boards like this existed and guidance was obtained primarily from sales staff at local retail outlets. This can be very dangerous guidance, especially for the anxious rookie with a tank full of dying fish at home. Guidance on these boards can be equally dangerous if not used properly but we are least given the opportunity to gather as many opinions as possible in a short period of time. Sure, there are alway different opions and the occasional "clash of the Titans"...
I guess what I'm tryin' to say is that a U.V. sterilizer would not be placed high on my list of priorities for required equipment to successfully maintain an aquarium.
Multiple unit systems are another story, where new arrivals are "ticking time-bombs" and given the space limitations to accomadate new arrivals, quarantine practices are not always an option. Not to mention the common desire to turn the inventory over as soon as possible to reduce losses. I'm not saying thats right but it's reality. U.V. in these situations is certainly a logical "preventative measure".
U.V, like many other products/practices in this hobby, has it's place.
Where do I vote for yes and no...
