I am building my stand for my 13 gallon cube tank this weekend. This will be the 3rd stand I have built. Every other time its been a traditional stand with doors. This time Im doing it with a modern style to it and I want the entire front panel to come off. Thinking about attaching the top of the door with two magnets and the bottom will just rest on a piece of wood. What type of magnets can I use and where do I get them? Does home depot sell what I need?
