    How to install a 3D aquarium background?

    The installation of 3d background is really easy. Our 3D backgrounds are made from poly-resin, which is very durable material and sinks. You just need to slide the background inside your aquarium.

    ***Note- Measurements given on our website represent the back of the specified tank size(s). The background will be slightly shorter than the tank to allow it to fit within the support braces and plastic/glass trim around the tank edges, and allow it to stand up against the back. The difference in width is occupied by mesh to prevent fish from getting behind, and the height can be adjusted by leveling with gravel or small slate pieces. It can also be modified or trimmed using a dremmel or sander tool if needed.***


    You can have water in your fish tank, even fish and other decoration. It's recommended to drain some water to avoid spillage during sliding the background inside your tank. You can squeeze the background inside the substrate, so it will support it. The background will not fall off, it's stable and will not move. No silicone is required, but if you prefer to silicone it, you may do us, but you will need to empty the tank, dry it off etc. The thin rock backgrounds are very slim around half inch thick, so some fish keepers prefer to silicone them inside, because it's not possible to hide anything behind them - they are almost flat on the back, but don't sit flush to glass. 

    If you need to adjust the background, trim it or cut the holes for pipes, you may use angled grinder, hack saw, dremmel to trim it down. The holes can be cut by using normal concrete drill or round tile cutter. Make sure you cut the background outdoor and use protective glasses and gloves. After cutting the background rinse it with water. There is no need to seal the background in the cutting places - resin backgrounds don't leak anything to water.

    Here's the video how to fix the background in couple of sections and to make the seams invisible. Video done by one of our customers, thank you Tazim. 

    If you have support braces you will need background in sections, which means that we cut background in 2 halves or more sections. The line of cut is straight and we can't cut in any different way. The seam is visible, but you can use silicone in the seam and squeeze both sections together, so it will become almost invisible. See how Tazim did it in his fish tank.
