I would never have believed a tank made of plywood if I hadn't visited GARF's site. This gives all new opportunities to those of us with building skills and little dinero. It also allows for some interesting tank shapes and set ups. The tank size calculator and parts list is a life saver. Has anyone tried the garf grunge in a salt tank? I was looking at the ecosystem hang on style of filter that uses miracle mud as the filter. It supposedly does not need a protein skimmer, less water changes, and can be used on both fresh and salt.
