The Filter Mats measured 1 meter by 2 meters were cut into 5 pieces measuring 20" by 30" These were then stacked together and placed on top of the plastic supports in the filter sections.
Hope that the pictures showed them clearly.
Some cement blocks were place on top of the mats to hold them in place against the water flow.
In the pictures they are the little cement cubes in the water on top of the filter mat.
