About Us
In reality, CaribSea began in 1950’5 Cuba where Greenfield a Navy fighter pilot and early adopter of SCUBA gear, and his wife Nancy were stationed. Both were California natives with a taste for adventure and diving the fabulous reefs of the south coast of Cuba was a natural. Florida was the epicenter of the emerging fiberglass boat industry and just happened to be the best diving in the continental U.S. South Florida became home and the Florida Keys an every weekend destination. The home aquariums multiplied but a high quality substrate was always a problem and, as it turned out, a problem for everyone else too. With so many potential materials available and the proximity of a world renowned marine institute and laboratory just down the street (the University of Miami’s Rosenstiel School of Marine and Atmospheric Science), a product was born.
Now CaribSea Inc. is in the hands of a second generation of aquarists, scientifically trained and with decades of experience. Since 1975 CaribSea has remained on the edge of closed system development by matching substrate mineralogy and hardscapes to the universe of microbiology. When I see a living coral reef thriving in someone’s living room and reflect on the primitive systems of our past, I have the satisfaction of knowing CaribSea played its part in the revolution. CaribSea is constantly changing and evolving but what remains the same is the commitment to producing the most advanced and very best quality products in our field.

First: buying live sand yes, it has good bacteria but when you ship it NO MATTER what, some bacteria will die. Putting sand in a saltwater bag doesn't mean it will keep all its bacteria, you need light, aeration, water movement and exporting of nutrients (this is what we do in our saltwater tank). Its FALSE to say moist sand or mostly dry sand doesn't have good bacteria. This particular product is Carib Sea Ocean Direct NOT their old version of live sand. This doesn't have liquid water in the bag; this has just moisture or mostly dry sand...which still has bacteria.
So my point, you get good bacteria and also lots of dead bacteria which will contain Ammonia, nitrites or nitrates. When adding to the tank it will "crash" your tank (quote from other reviews), it puts ALOT of strain on your already established system.
**Note if your adding this sand to a brand new tank (no life) then this is what you want.
Long story short, WASH this sand if your adding to an established tank!
Lastly: people who complain about cloudiness, this is the nature of the beast when buying any sand. Wash the sand! You will still save some bacteria, especially the live bacteria that's attached to the sand and in the process wash away any dead material not attached.
Conclusion, i added this sand to my established tank after washing it for about 5 - 10min and after 1 hour it was clear. 4 hours it was perfect. Over the week i saw zero change in ammonia, Nitrites, Nitrates and phosphates. *i did attach my filter sock for the 4 hours
This is probably the best value on Amazon for calcium carbonate based aquarium sand from a trusted manufacturer... it was when I bought it anyway.
Regardless, this is excellent reef or African Lake Cichlids that require high carbonate hardness and high pH water. Oh, and aquarium husbandry is more about keeping water chemistry consistent with the needs of its inhabitants than anything so don't complain if you just can't seem to keep any Neon Tetras alive in your aquarium with this sand (your neon teras that only thrive in the tannin stained, low-pH environment that the Amazon River is).
Yes, like any other calcium based sand that I've used in my 12 years of reef keeping, professional or personal, this sand will definitely cloud your water for about a week (if you actually have flow like you should in a reef tank).
You've been informed.

Other than that I am happy with it. It is very fine but that works well for deep sand beds and substrate critters. Overall I would say a good buy, but just make sure to put it in a 5 gallon bucket and rinse it VERY well before it goes in the tank.
