Well I started in 1986.....so how many years is that?? Not consecutive unfortunately....breakdowns occur because of moves I'm not really sure those should count as breakdowns since they were moved and set back up immediately. So first run was 1986-1996, second was 1996-2001. I did take a break from 2001-2004 but been back up and running since 2004 and that includes a moved from Detroit to Dunwoody and then Dunwoody to Johns Creek.
And to give some idea of changes in the hobby...my first filtration system was a reverse flow, undergravel filter!
