Here I am setting sail on the $30 solution boat! This is for a 30x18 56g column tank.
The stand is pretty well level as it sits without weight on it, but we'll see where that goes. I think the whole place is a little off in that department. I ended up leaving a 3/4" lip all the way around.
I've got about 6" of space between it and the wall. Does that sound like enough or should I adjust it? My primary filtration is going to be a Fluval 405. The pink foam there is just to represent the footprint of the tank so I could mark where it needs to sit. It, and its little passenger, won't be staying
