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.

Any coating can wear off in time. The problem would recur. Many chemical manufacturers (Glaxo, Bayer etc.) make non-toxic algi-cides. One can try these after monitoring if the fish are affected in any way.

I noticed that when there's a scratch in the glass, the algae really love to grow there. So I would assume that for growing on a surface, they need some sort of crevice where they can find hold. So maybe it's possible to make glass or some other material so smooth that they can simply find nothing to hold on to? :-?

Hole in one, Steve. That's exactly how it is. Any roughness provides an anchor, or a nucleation site if you want to put it that way. Once a little bit gets a toe hold this starts collecting friends and relatives, form a colony, stands for election- what not. If you could produce an absolutely smooth surface then algae will not start. A liquid covered surface is what they call 'labile', which is smooth at a molecular level.

The solution would probably be a hydro-phobic, very high viscosity coating, which can be sprayed on to the inner surface of such containers. The coating can be diluted by a suitable carrier for spraying or one can design the coating to be formed only after it is sprayed and reacts with air.

I agree with you from your other posting that it is stimulating to speculate.

put a snail in the tank.

Another possibility would be to add a compound/chemical to the glass during production that would discourage algae from growing. Of course this compound would need to be insoluable in water (and saltwater) and nontoxic to desired biota. It might take more than one compound to reduce most of the algal taxa.

This is a great idea!. ;-D i know that for the slightly slovenly people such as my sister who owns a fish in a tank, this ides could save the poor fishes life!

Whenever i visit her i stick my hand in the tank and wipe the alge off. the snail idea is pretty good too though....or even a sucker fish does a good job. Mabey someone could even incorprate an anti-fungal glass and you could buy special tanks.
good idea.
