Need to? No. To me, one of the perks of the sump is to get rid of as much stuff hanging on the tank as possible for aesthetics. There isnt any reason you cant use it in the sump or, as paul suggested, use it on a qt or some other tank. You can also keep it handy 'just in case' something went wrong with your pump although I would keep the filter media in the sump so you will maintain some of the beneficial bacteria if you ever HAVE to use it and avoid cycling the tank.
