No, in a filterless QT, NH3 can build up in less than a day. Weekly water changes often aren't enough. As for HOB filters, they can also be HOF or HOS, you don't need to put it on the back. At this point there's no point, unless you have a piece of mature filter media. It's a good practice to keep a foam block in your sump for times that you need it.
