After I get my het albinos in, I think I will be going to tubs. As it stands, I have 4 tanks on top of furniture in my room and soon to have to add 2 more enclosures and whenever my large BCI comes home, that is just a huge 4x2x2 tank that gets thrown into the mix. So...I decided I will build a rack. I think I want to do with with Sterilite 1960's for any larger BP that I may acquire and do one with with maybe 1756's(23.5x16.25x6 3/8). Flexwatt 11" flex watt on one side of the 1960's and would 3" work on the 1756's? Both racks hooked up to it's own Johnson thermostat
