Play sand? I never heard of using this as a substrate and sounds a bit messy. I know a lot of people use charcoal under their soil (I did). I posted pictures of what I used on my profile page. From bottom to top how I built my substrat layers: false aquarium bottom, hydroponic clay, fiberglass mesh, charcoal, fiberglass mesh, then jungle bed blended with forest moss and orchid bark.

I was going to post a topic on fish. I was a breeder ages ago and have a couple suggestions. I noticed a lot of people use goldfish because they're hardy. But I tend to find them a bit messy and big time water polluters. Just have to use enzyme treatments to help with the ammonia balance. =)
