New tank, stand, canopy from lfs
about $700 - $1,000
Now add a skimmer, 100 pounds or so of base rock, another 100 of LR
, a sump, pump for return, two heaters, sand for DSB
?, a few powerheads for circulation. Call it roughly $2,000 - $2,500 or so for new equipment.
Buying used or DIY
items will change that considerably.
Oh, there are no lights in that estimate.
