You could use crushed coral in your calcium reactors second chamber, but most calcium reactor media you will find is going to be a bit cleaner and rinsed from organics and other nutrients that you may not want dissolving in your aquarium.
Caribsea's Arag-Alive! Live Reef Sand is a great choice for new aquarists and new reef tank setups. Arag-Alive sands clear quickly and contain millions of live bacteria, speeding up your tanks cycle and leading to less nuisance algae.
Selecting the right sand: When choosing the right sand for your tank, it is important to keep a few things in mind.
How much flow will be in the tank?
Aquariums with high amounts of water movement will require sand with a larger grain size. Smaller particles can be blown around easily.
What kind of inhabitants will you be keeping?
Many species do require particular types of sand, like gobies, jawfish, and wrasses. Fish and invertebrates that like to burrow or sift through the sand will do best with smaller particle sizes.
Will it be for a refugium or deep sandbed?
Sand that will be used for filtration or refugium, we suggest using smaller particles that will give bacteria more surface area to grow and thrive on.

Great Looking sand By Joshua on 5/8/2017Joshua would recommend this product to a friendLove the way this sand looks. My tank did not take long to clear up at all. I'm looking forward to see how my Goby will do with it, once I get it.
Not a fan By Mark on 1/14/2016Mark wouldn't recommend this product to a friendMight just be the bag I got but there where huge chucks of rock in there roughly finger size. Took 3 days to settle and was still getting blown around. Replaced it with special grade and loving it. Ill never grab anything else.
Good Looking By Phil on 5/13/2015Phil would recommend this product to a friendLayard this crushed coral over Fiji Pink. It is very white looking and I had no problems with cloudy water. I put just enough water to cover the sand in my 30L Nuvo tank then slowly added the sand and let it sit long enough so that it settled. Then added my live rock. I carefully added my salt water slowly letting it fall off of my live rock. The tank is in the process of cycling as well as the live rock at the present time, 17 days so far. Nice white bottom and coral is large grained.
Nice Looking Sand By Philip C on 11/28/2014Philip C would recommend this product to a friendOrdered this crushed coral to put over 20lbs Original Grade Ocean Direct Live Reef Sand to make a more attractive bottom in my 20 gal tank. Probably should of only put 10lbs of each in tank as I now have a deep sand bed. A couple of bristle worms showed up a few days afterwards. I took them out only because they don't look good in tank. This is a new tank with damsels that I removed from my 40gal reef tank so that I could put more peaceful fish in it . My original sand had settled down after days of horrible looking water from my new pukani live rock. I removed my rock and layered the coral over the sand and it did not take very long for the water to clear. The white coral makes a good looking bottom.
12 months old By Philip C on 11/17/2014Philip C would recommend this product to a friendWould recommend if fresh sand but the 10lb bag I got had an expiration date of Dec 2013. Supposedly this bag had a shelf life of 12 months. I just wanted it to add a top cover for 20lbs of sand I had put in my tank. Even if the bag was fresher, it probably would not contain live elements because of the bitter cold it arrived on .Was ok for my purposes and makes the bottom layer of my tank nicer to look at .
It still fell into the 12 month shelf life as it is still shy of Dec 2014. So I would still recommend it to a friend and still recommend BRS products on the whole. Good looking crush coral.
