Tank with longer walls transparent made in acrylic/plywood tech. This is a less expensive solution that all acrylic tank and effective when one or two walls are to be visible. Hydro-insulation can be long lasting if done right.
Additionally, plywood is as easy to treat as acrylic. This tech is therefore applicable if there is no possibility to deliver a big tank as a whole. In such a case, we make a body of the tank on site and then install single acrylic sheets.
