Normal pots for household plants are likely too deep and provide to little surface for our needs. Other fish produce a lot less waste than goldfish, but they still do; thus vacuuming frequency can be reduced.
Since you are doing some basic cleaning of the tank I would suggest go all the way and set it up like a proper tropical tank. It would be less of a hassle to do it now when you do not have fish in it.
