Green algea - How to get rid of it

[trand]

Hi all and Happy New Year, bit late I know, anyway the drive that was done last year got through the winter with no expansion in the cracks, (pics can be seen on here), they did try grinding it , but to no avail , and had to rip up and replace the drop kerb area, then I got a massive discount on the hard standing, trouble is we get a lot of green algea here bloody murder, on concrete areas and brick work, any ideas how to get rid of it and keep it away apart from bleach and jet wash ?

Are there any trees you can remove or prune to provide more sunlight less shade?
