If there is one this that I hate about a fish tank, it is being able to see the wires that run behind it. All those store bought backgrounds don't really float my boat to much either. So I got an idea from a friend.
Here is my DIY background. It is spray on, and it is permanent.
-"stone touch" spray paint (found at walmart, lowes, etc)
-Flat color spray paint (to match stoneworks)
The first thing I made sure to do was to properly clean the back glass with alcohol.
Then I masked of my tank
Next was applying several coats of the "stone touch" spray paint. (Back outside glass of tank)
after letting it dry I then sprayed "Flat gray" paint over the other layers to fill in the holes
Waited till it dried, then removed the masking tape
here is a close up of the texture that will be seen in the tank
and here is the tank right after it was set up
Other spray on backgrounds I did the same way (just different color "stone works")
I hope yall enjoyed
