This 3D model was originally created with Sketchup 13 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 System 1 consists of reservoir 500 for fish l, 2 drums 50 l, 2 bombona halves 50 liters with a 2000 l / h pump. This is a basic system, a system really for beginners. One can add filter solids, biological filter, but in the beginning is not really necessary. The design of the tank is 500 l, but can be easily replaced by a 250 l in which one could easily reach 10 kg fish. Biological filtration to give the substrate cultivation beds, and filtering the solids well. With time the solids will accumulate in substrate cultivation beds, but can be removed only with a washing of this substrate. The ratio of the material and the necessary parts can be found at the link below.
