I just realized my post could have easily been misinterpreted. What I meant is that if all you want to wait is another month or 2 don't waste your time and just pull the sand now because it will likely take longer for it to establish. There is nothing wrong with the sand, it just needs to become established. You have a ton more sand than I had and mine took a good 6-8 months, just like my rocks did before all the crap started to go away. Even then I still see it here and there. Realistically with a sandbed that big, some maintenance will be needed. Its great sand, but anytime you start with anything "dry" rock or sand it takes 10 times longer for it to settle in.
