STS handles just like SMS and Turface. I just put it into the tank without rinsing ahead of time. I partially filled the tank and drained it, rinsing the STS that way. Water sure was cloudy! It looked like there was a mix of particle sizes in the bag, and I am not surprised at the cloudy water.
Color is rather nice. Looks like soft grey and medium brown when it is dry, gets a bit darker when wet, and not so dusty looking.
I am going to stir it around one more time, and rinse it once more, then go on with the next step.
40 lb bag was just enough for the tank I am working on, 5' long x 16", and the substrate is barely 2" deep. I might mix some Soil Master Select, charcoal with the STS. It would make the blend just a bit darker, and add volume. Or maybe a few large rocks would displace just enough to make it deep enough. It is right on the edge of being deep enough already, but a little more would be nice.
