I picked these up from a store that was closing down. I won't be able to use them anytime soon so I'm passing them on. Each unit holds eight 15g tanks. In the picture, they are not using the very top shelf. The units measure 51" long, 13" wide and 72" tall.
I have three units. Each unit comes with: Six 15 gallon tanks drilled on the bottom 1 sump An external pump (Not sure if these work, but feel free to take them) The bulkheads and standpipes
