Just registered and saying "Hello". After many years in salt water I have decided to try a freshwater biotope tank. Alot of similarities between the two disciplines but enough of the unknown to keep myself challanged. I enjoy the mechanical aspects of modifying, designing, and building my own components. Biological filtration along with water changes is the only way for me. I strive for "as natural as possible" in my approach. Looking forward to learning and making new friends along the way!
