Removing the read more from excerpt

Hey everyone,

I have managed to set the length of the excerpt but I want to be able to remove the read more thats added after it, so that there is nothing after the … of the content.

This is what I have at the moment.

function custom_excerpt_length( $length ) {
	return 30;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

Hope someone can help!

Thanks
