Used 60 gallon tank. Holds water, has hard water build up as common to old glass tanks. Been used for a quarantine tank for some time now. No glass tops.
When I have filled it up to the trim, I noticed there may be a leak up there, but I keep water level 2" below trim and never a problem.
$25 (Tank only, no accessories included)
