Someone explain this to me
It is an efficient, stand alone substrate. Why would you want to cap it? There has been a lot of chatter about mixing it with other substrates and capping it. I continue to be very confused as to why someone would want to do that? Would you explain to me, sixerfan?
Realize this. When you are mixing substrates, the smaller grained of the two substrates is going to work its way under the larger grained substrate. Unless some sort of barrier is placed between the two substrates, the mixing is inevitable. So, your sand over your Aqua Soil is going to wind up being your sand under your Aqua Soil.
