Instead of waiting for colorquartz from 3m, I went to the local pool supply and bought 200 lbs(4 bags) of white quartz filter sand (45-49 grade). I poured it into the tank and it looks awesome. The tank is a little cloudy but I will post a pic once it settles. 200 lbs seems like it will give me an even 3/4 inch cover on my 96x48" foot print. I'll spread it out once the cloud settles and see if I need another bag.
