Is it a bad idea to put a saltwater fish tank right next to a window?

The tank is going to have a blue plastic background and tin foil on the back to block most of the sunlight. I am going to give it a try and if it does not work I can always move to a different area.

I have my 60gal FOWLR very a large window. it has no backing. in short, yes algae does become a problem with all the sunlight although temperature swings have not been a problem for me.

I would definitely have a heavy curtain on the window. that way, if you want to cut the lights for a few days to kill off algae, you can do it without sunlight mucking up your plans.
