First, I would like to praise Tim, he is constantly trying to do the best he can for his tank and researching as many options as he can. This however brings many differing opinions on this board...Its hard to sift through all that info and try to pick whats right for an one as an individual.
Tim, UV sterilizers have been debated many times as to effectiveness, benefit, and detriment. However, those that use them will be the best source of info on there use and effectiveness! There may be many reports, and official studies, but the bottom line is actual experience, such as you will find in many things in life! I do not use a UV unit, but I have as yet, not had a reason to, if/when I should have any disease issues, i would seriously consider one, as several friends here have used them with good success, and no problems other than maintenance issues like the bulbs, cleaning etc. When you think of the cost vs benefit, if about $100.00 can add a significant decrase in disease than in this hobby thats a good invstment especially since you can easily turn it on and off when you like!!
As far as your Kent Biologist contact, good for you! trying educated other options are a good idea IMO, if things work out well, then we all will benefit from your experience. Be aware others will still be skeptical, as they have not used or have little info on this type treatment and other types have worked for them. The only way we can further this hobby is to expand our knowledge by educated trial and error, and I believe you are on a beneficial path..
Good Luck, hope all works well and will be following your posts on this!!
