I tried that but by the time my window gets sun it's late in the day and I can't move the tank ;; Maybe I need brighter lights.

Pothos in filter. Extra water changes.

Since beneficial bacteria are sticky and adhere to all the surface areas, in the top layer of the substrate and in the filter media-very little are in the water column. A UV light won't hurt your nitrogen cycle since they are designed to destroy things in the water column as they pass through the UV light.
