Yes, you can. If - and only if - you have the tank planted. (yes, it's my current fad, but hear me out)
To go totally filterless, however, I think you need to have the plants established and growing first. Your big problem is that IIRC the water in Leicester is like liquid rock. Plants don't like that. But it's only six gallons, so bottled water is a possibility.
