Hmm.. Flourite by Seachem. I've seen this product at many pet stores. Not many people would buy them because of the feedback given that it doesn't really work well. People would rather spend their money on Amano's substrate gravel.
Well, to solve your problem a bit.

I'd suggest doing all you want to do first such as adding the plants, decorations and editing it here and there before moving your fish in. So that you can finish everything without bothering the sand later, then when it clears up completely, you can add your fish. I wouldn't add them while the tank is still cloudy because when they breathe in the water, the sand particles might enter their system and either choke them or just make them unhealthy. So finish everything you have to do in your tank, and when you are satisfied and happy with the layout and you know that you won't bother your sand anymore, you can add your fish.
Hope my suggestion helps. GOOD LUCK and keep us updated.
