almost all hoses are 'curved' because they come in reels. you need to lay them straight and allow them to 'forget' their curvature.
using hot water should shorten the 'straightening' process.
Are Eheim external filter hoses more flexible than generic ones? I'm looking to buy good hoses that aren't "curved", as in you can lay them flat in a straight line on the floor. I read that someone put them in hot water and the hoses can be straightened out. Any truth in that?
