I am looking to use something like the Benchmaster 96" x 24" Black Plastic Grid Top Platform Panel (650 pounds support) to create voids in my bogs instead of pallets. I like the idea of a clear void vs the aquablock style of a grid of support. I might just be creating more work, but a clear void under the gravel seems better for cleanout. I have not seen a lot of documentation on others using the approach, so while I don't like being bleeding edge, it does seem cleaner to me. I have not done it yet, so just theory right now. Still planning my new bog areas.
