redfishbluefish thanks for posting the links, as had lost this list when old PC crashed. A few years ago I spent several hours reading Randy's three articles on Ozone before being comfortable enough to set mine up. And on regretting not continuing my education during the 80's in Marine Science have read many of the other articles/publications over past several years as well. Definitely a Science Geek at heart and what has drawn me to and kept me in this hobby for so long.... so much more than what meets the eye or way beyond just 'Pretty Animals'.
Cheers, Todd
