So I am in the process of converting my 30 gallon SA/CA tank to a african tanganyika tank and I am in the process of making a 3d background. I would use pool sand for the tank but i want black colored sand. So i looked around and found that 3M doesnt make color quartz any more but this Company makes Spectraquautz I was wondering what grade i should get or if this stuff works also i can't find a place that sells it should I look at pool stores? or what?
Or if some knows of a better cheap colored substrate.
