10g AIO help

[Erik2514]

So I've been out for a while and want to start a 10g AIO. I have so many extra parts lying around and just want something small for the time being. My question is what is a good light for a nano. I would like the option to be able to keep any coral I want but at the same time I don't want to break the bank on a 10g. I have a 165w dimmable Chinese but feel that would be overkill. Any other suggestions?*
