I have about 1/2 a bucket of this sand (maybe 3/4 it's been a while), I got it from petco and was sold as african cichlid sand @17$ a bag. It needs a bit of a wash but other than that it's good to go. Looking for 5$ or a zoa frag (something blue). I will weigh the sand when I get home from work. Here is a picture of the sand.
