Pebbles on top of leaves on top of dirt
And now I added a thin sand layer over the pebbles. As measured from the side of the 33 gallon sterilite container, the dirt/dried grass mixture was 9". Then there's 3-4" of leaves. Then a rather thin gravel layer, then a thin sand layer. I use a bubbler, and there's just a few inches of water in the container above the sand, which I use to mineralize rainwater for drinking (mixing that with rainwater in a cup). The sand layer keeps the water clear. Also, I didn't add 9" of dirt initially, there was a lot of dried grass mixed in, and it spreads out a bit under water (by the way I also left the container outdoors in direct sunlight for 2 weeks and it composted the dried grass clippings inside, but also grew a lot of algae, and the algae took three weeks to die down once brought inside in a cooler area.
But what I noticed was interesting was at the end of leaving it outside, there was some foam floating on top, like at the base of a dam, that came from composting the grass, and the container was filled up with water the whole time outside ie didn't have sand or pebbles outside).
