How long has your current (primary) tank been running?

[Delphinus]

I get to vote 1-2 years because that's where my current primary (280g) is at .. prior to that though the 115g and 75g tanks it replaced had a few km's on the odometer. 115g at around 6 years and the 75g made it close to 9 years or possibly beyond (I can't remember if it was 2000 or 2001 that I set that one up .. I think it was 2001.). The 75g itself replaced a 50g that was setup around 1998. So while I can't top a 24 year old coral, my oldest fish are my clown pair at around 14 years and my tang is now 11 years in my care. Time flies after a while.. Heck my "new" green gigantea carpet is now at 8 years (purchased 2004). Wow, it doesn't feel that long ago I was telling someone on RC about it being 2-3 years in my care. Holy schnike!

IME, things do get more difficult at the 2 year mark. Accumulation of things, and failure of things. Tearing all the rock down and replacing it counts as starting over!

V2 of my tank is at about 1 1/2 years old.....V1 was 3-ish years old before the move/crash
