Remove padding on top of Blank template page, one page only

Hi guys,

On this page – http://godiaperfree.com/go-diaper-free-week-2014 – how do I remove the padding on top (seems to have come default with the standard “Blank – No Header, No Footer” template) without removing padding sitewide?

First I did this in Quick CSS:
.html_header_top.html_header_sticky.html_large.html_bottom_nav_header #main {
padding-top: 0px;
}

and it worked for this page but negatively affected the rest of the site.

However, adding the page id like this didn’t work on this or any page:
.page-id-6530 .html_header_top.html_header_sticky.html_large.html_bottom_nav_header #main {
padding-top: 0px;
}
nor did this:
#page-id-6530 .html_header_top.html_header_sticky.html_large.html_bottom_nav_header #main {
padding-top: 0px;
}

Thanks!
David
