The goal was to make the cabinet look as ascetic as possible. I've decided the cabinet should be lower than standard one something like 70cm, because usually I'm sitting on coach looking the tank, and that is proper height in my case. The project is really simply, the only two things are different from standard attempt. The base is made from double mdf (screwed together) and under the base is sort of beam made from 3 pieces of mdf the same size (again all three pieces screwed together) and screwed to the bottom of the base to prevent bending the base. Looks like too many effort for 112l tank but I've decided to paint the cabinet, and to prevent small cracks on painting tha cabinet has to be pretty stiff. The fish tank base is ~70x40cm (69.5x38cm).
