My current tank is just over 6 months old. However that is because we decided to do a small upgrade from the 3g pico (4 years old) to the current 300g system.:wildone:
Exactly 20 years old.
Not to hijack the thread, but I would love to see some pictures of these tanks that are 10+ years old. The same tank though, not one that has been constantly upgraded with the same rocks and all over the years. There's just too many variables with these set ups IMO.
