A very good substrate in my 65 gallon reef. I only wish they made the instructions of needing to wash it off prior to use bigger. It comes damp/wet, so I assumed this was the ready-to-use stuff as with other live sand. After filling the tank bottom and adding water, the whole tank filled with the fine particles which took a couple days to clear. The fine particles covered my live rocks, and took a little bit of blowing off with a baster to clean up. I think I finally have it under control. Great substrate, just make sure to rinse out in a bucket prior to use!

This sand is very pretty in color its really light like almost a white but not quite. The grade is nice the snails and starfish seem to like it. When you have your night lights on it kinda glows in the dark. The price was fair and it doesn't cloud your water too much in 24 hours my tank was clear and within 2 days it was crystal clear like the fish were swimming in thin air. I did rinse this sand before adding it to my tank. I would recommend this product to anyone and I would buy it again. The only thing I did miss when I put this into my tank and added the water was the smell of the ocean didn't get that with this sand? other than that it is great stuff.

The substrate is superb, and comes ready to set into an aquarium as is.... The only thing that bothered me was the weight... just kidding of course, I mean for 40lbs it was sure worth the money. Satisfied.
