I don't care for the look of bare bottom, but as long as there are no burrowing or "earth-eating" type fish in the tank I can certainly see the benefit from a maintenance aspect; I have several tanks myself that I keep bare bottom for that reason. But I don't like just the smooth glass or epoxy (or in your case, acrylic) surface. I usually use 12-inch ceramic tiles to cover the bottom; just fit them carefully in place, cutting a couple at the end to get a nice fit. I like the rough-surface, textured tiles.
I always run a tiny bead of silicone all the way around the bottom surface of each tile, maybe a half-inch from the edge, and then set the tile buttom-surface-downwards on a sheet of waxed paper allow the silicone to set. This creates a thin silicone cushion on which the tile sits, hopefully to prevent detritus from insinuating itself underneath. I then lay the tiles in place with the tank at least half full of water, so that the gap underneath is filled with water rather than air. I never had an issue with debris building up under the tiles, and when doing a bottom siphon I run the mouth of the tube along each seam to suck out any that settles in the gap...although I frankly think that this is a waste of time as very little comes out. I actually siliconed all the joints between tiles on one tank, but now I am always expecting to break one of those tiles, so won't be doing that again...
Another thing I have toyed with is using one of the textured "luxury vinyl" type floor tiles. They are completely waterproof, much lighter and thinner than ceramic, look great, and have enough texture to them although they aren't "sculptured" on the surface like my favourite ceramics. They snap together at the edges so they can be made into a solid floor, rather than individual open seams between the tiles. I have no idea if they are non-toxic; I have a tank set up with them for a few months now and no problems...so far...
