I joined because I use the forum information all the time and finally realized I should just become a member and really participate.
I have an in-depth knowledge of filtration and biological processes as I studied water treatment as an Environmental Engineer a life time ago.
I have three tanks, 2 x 10 gallon freshwater and 1 x 30 gallon freshwater. I really enjoy the live plant aquascaping side of the hobby. I look forward to learning from the vast wealth of experience held in this forum.
