Nope, had nothing wrong with it. They sell this really cool cichlid type sand, I bought it for my 60 gallon cichlid setup. It's black and white and it's really cool and fine grain.
The cichlids love it and the pleco does too. In my 55 gallon I got the river sand and you see little dents in the sand all the time from the cories diggin in it. Cories will love it.
I suggest not mixing anything with it. I thought I would to, then after only a couple of weeks I hated the mix and had to take all the gravel out, TOOK FOR EVER! I suggest no mixing at all. Just get your sand and put it in and leave it.
