Thanks for all the positive reactions from you all! But ít's with the help of all of you here on MFK that I got the idea to start it all.

So some more pic's of the build.
In the picture above you can see that the background is placed in the tank, to make sure it fits correctly. I then put on epoxy on the background. It's the same epoxy I used for the tank. I put on two layers of epoxy.

The whole background is coated. One cave is in the upper part of the back wall is still white. There are three caves for dwarf cichlids. The lower part of the wall (still wet from the epoxy) then gets a layer of reddish terrarium sand. The area above the red "rock" gets a coating with matt black terrarium sand.

After that, the whole background was lifted out of the tank. You can also see that the upper part now has the matt black sand on it. It's time to get all the styro and polyurethane off from the epoxy. This to create enough room for the filtering and equipment behind the walls and to reduce lift when underwater.

This stage was a lot, a lot of work. The entire room was covered in styrosnow when I was ready. And it took a few weeks to get this done.

nice looking background i once tried a small background and failed horribly so you must have put some man hours into that thing

Yup the background took a lot of hours.
Actually it took a lot more time to finish than the tank itself!

Especially removing all that styro and polyurethane was very time consuming. The epoxy layer is quite thin, so when removing the styro/urethane (with knife and router bit on accu drill) I went through the background numerous times.

All those little holes then had to be filled with thick epoxy and the bigger holes with some glass fibre matting. That also took lots of time.

you know i didn't even think to use black epoxy to cover the background with,,, you have just giving me more ideas then i know what to do with right now,, i used cement on the background i made for my 180gl it was a pain, using cement you loose alot of the detail that your were going for thanks
