As long as my hubby cannot read these....OK, 1st tank, 50 gallon long tank and stand were used, with rock and lights etc. around 1000. I cringe! We have two at the moment, a 29 g and a 90 g, withthe first one condensed, the 29 is at around 400. And the 90(used) is at around 600. Its so hard to break them down when I only put MH over the 29 (taken from the 1st 50g., part of the time). The 90 g is just starting to turn reef with one set of T5'5. I got a lucky break with rock and like 5 fish for 50 bucks on that one! really kept the startup $ down.
