on the back it says to pre-soak it unlike normal sand that you need to clean quite a lot. So far all it's done is make a foam on the top of the water. If you drain off the black foam(black sand) and refill you create a new layer of foam.
Anyone ever used this stuff to tell me if it eventually sinks properly or if it's just a garbage product?
