My plan is to create a 20'x30 flat in about 3' of water (full pool). I also plan on placing a tarp or landscape fabric over the area to hold the material in place and not let it sink away over time. The big question is what material should I put on top of the fabric? pea gravel? sand? mixture there of, something else?
Looking like gravel may be the way to go.
