Installation instructions for a Back to Nature Slimline background



1/ Combine the sections you need (see table below) to cover the back glass of your aquarium. You may use the various sections in any order. All combinations are possible, as all sections have unique straight edges and overlap for interlocking and hidden joints.


2/ The “final” overlap to reach to the edge of the aquarium should be trimmed, in order to make the background fit evenly with the side glass.


3/ Cut from the backside. Use a sharp thin bladed knife and cut firmly 5-10 times in the same track.


4/ Then carefully break off the excess material. If you haven´t cut deep enough the hard resin front may not break cleanly.


5/ If there is a lot of silicon in the back corners of the aquarium you may have to cut away a small part of the background in order to make it fit both the back - and the side glass.


6/ Check that the background fits the aquarium correctly.


7/ Fix the background by using 10-30 fairly big lumps of aquarium silicon sealer on the back of each section. Begin with the piece that you just have cut to fit the aquarium


8/ Press the section firmly onto the back glass. Make sure that the upper part of the background is placed approx. 5 mm above the future water level.


9/ Now glue the other sections of the background in the same way (begin with the section that is closest to the section that has already been installed), but on these sections you should also place a thin line of silicon on the backside of the overlapping section.


10/ Wait for 12-24 hours until the silicon has dried. Then you can fill the aquarium with water.
