After installing 3D background inside your tank you will have plenty of space, between background and glass of your aquarium.
There are gaps to run filter pipes behind. You can run water inlet pipe under the background, so the tip of inlet is in front of the background.
The outlet can be mounted in top corner of aquarium.
Heater can be also hidden behind the background. If you have a good filter, water will circulate around the background and the heat will be
distributed everywhere. If you want to increase water circulation behind the background install additional power pump behind the background
close to the heater. The warm water will be pushed out and will not become stagnant.
See our blog post with pictures, showing how to hide equipment behind the background.
