Funny this topci should come up....I got some aquarium backing for my 75gall tank today....I got....MATERIAL!!
Sounds weird I know but the choices were endless...it is cheap and can be easily changed.....
What I ended up with was a medium/royal blue colour with silver stars....I think it looks prety cool....I attached it to the tank with pegs (above the water level)...
I shall be taking pics VERY soon
