I have built an inground swimming pool of size 20x10x5' without bottom drainage/skimmer plumbing. Need guidanc

I have constructed an in ground swimming pool of size 20 x 10 x 5' deep without carrying out plumbing for bottom drainage/ skimmer for filteration & re-circulation of water. I have built this pool adjacent to an existing out door water fountain giving a cascading effect for re-circulation of water. I need guidance to provide filter etc. I propose to use canvas/polyester filter for filteration with cleanout window for cleaning. Can somebody guide me?
