Anti-algae glass for fish tanks
I noticed on just about every fish tank I've seen, a lot of the glass gets covered in algae and it takes a lot of time to clean. The glass of the tank could be covered in something which plants won't grow on.
I know it sounds simple and someone's probobly already thought of it but I haven't seen anything around like that.
