Hi Peggy,I bought your book and am getting good use from it. I recently purchased an odor problem, but am about to cure it using your info. I was wondering if you are affiliated with www.tek-tanks.com? I stumbled onto their website and noticed a lot of text directly out of your book. I will be replacing my holding tank and I thought you suggested a different company and so I was suprised to see the text on this site.
