I could see that, things leaching off into the water.

I looked at that web site a couple of years ago. There was an article in there about making your own rock pieces but it said that there was a long period of curing and water changes before the concrete stopped leaching. The plus side is that you can make the pieces to whatever shape and size that you need.
