I have decided that its time to move on from the cinder block stands and am looking for other options. I want to be able to display two tanks on one stand/rack and one on the other. I have 1 75 gallon, 1 40 gallon breeder and 1 zoo med naturalistic double door terrarium (36"L x 18" W x 18"H). If anyone has any ideas I am open to them all. It does not matter which tanks share a stand as long as I can open the terrarium.
