Somebody help, please!

I purchased a 54 gallon corner aquarium with a sump last November, I then had to wait until I could afford to get it going the right way, I purchased 120 pounds of Ocean Direct Carribean live sand, since I knew I was going for a deep sand bed. Me being ignorant and trying to do it the fastet way possible, I filled it up with the saltwater. Then dumped in the sand. Big mistake. My water instantly turned this gross brown color, not like sand. It's hard to describe. I'll throw some pictures in at the bottom. It also created a rediculous amount of foam. THAT COVERED EVERYTHING. yes, I mean everything. It's been running for about 2 days now, with everything on. And it hasn't cleared up one bit. Guys, I need help. I've never experienced a problem this big. This is a nightmare. Sorry if this is in the wrong forum, I didn't know where to put it
Thanks!
