You're fine Jim. Quarts will trap other elements inside it's crystal latice work and change the color. Out side of synthetic sand you will have color variations, but color variation alone isn't enough to indicate a problem, unless you don't plain to repot for the few thousand years it takes the silica to significantly desolve, lol. I live in the state silica sand comes from and unless you live here it can be sort of hard to understand the concept of natrally pure sand because everywhere else in the world it's not. In impure sand you have grains of non-silica minerals which disolve faster, but that isn't the same as when the silica cyrstal lattice captures and holds another mineral in it's cage because in that case the mineral can't escape the crystal.[b said:Quote[/b] (jimscott @ May 16 2004,8:19)]Thank you for fixing them! Please leave them up. The sand came from a place called NAMCO. I don't know if they are a chain or just a single store. I don't have enough experience to be sure if it is detrimental or not, although I haven't noticed any bad reactions from the plants. It does say, specifically, that it is pool filter sand.
