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.
How much sand do I need?
Below is a table of common tank sizes and how many pounds of Special Grade Sand is required to achieve a certain depth. Results may vary depending on the aquascaping in your tank, overflow styles, and the specific tank manufacturer. We always recommend getting a little extra sand to make sure you have enough on hand when you are filling your tank.

Perfect Size By Shane on 10/29/2017Shane would recommend this product to a friendThis stuff is the perfect size and will be my go to from now on. I'm very happy with this sand and how it was shipped. Thanks BRS for carrying a wide variety of grain sizes to choose from. aaaaa
Great Sand By WebCitz on 9/10/2017WebCitz would recommend this product to a friendMake sure you add this before fish - it makes an existing tank really messy for a day. Added this to a new frag tank and a bag to a refugium on a 2 week old tank. This sand is great - have used the oolite and special grade. Probably prefer the special grade a little more due to slightly larger size. The oolitr is like sugar crystal size.
Glad I chose it. By Randall on 4/15/2017Randall would recommend this product to a friendNot much you can say about a bag of sand, but I can say that to me, this is the most natural looking sand I've used. Filled the tank by pumping the water in over the live rock, and the tank was cloudy for about 12 hours. The sand stays put with pretty high flow.
Nice sand By Garrett on 3/10/2017Garrett would recommend this product to a friendThis sand is high quality, helps cycle your tank faster, and looks nice. However, after having it in my tank for a few months, I notice it tends to collect more debris than finer grain sand. I'd recommend mixing it about half and half with some finer grain sand. That seems to prevent the original problem, and helps keep the finer sand from blowing around the tank.

Good By Breezy on 2/7/2017Breezy would recommend this product to a friendIt worked
I highly recommend it By John on 10/27/2016John would recommend this product to a friendGreat product,, small enough to be sand and not look like gravel,, large enough so it doesn't blow around like fine sand,, I just put it in the tank last night,, this morning,, the water is crystal clear,, obviously,, I can't tell if there is actual bacteria,, but it's better than nothing :)
Da Best Sand! By Bobaloo on 9/10/2016Bobaloo would recommend this product to a friendThis without a doubt is the best sand I've used to date. It was easy to use and it helped with the biological maturation of my newly setup reef. I just pour in ALL the contents of the bag and within a couple of hours, my water was gin clear to see the shimmer of my Kessil lights over the new sand bed!
Excellent By Bob on 7/30/2016Bob wouldn't recommend this product to a friendWhen I set up my previous 120 gallon I used another type of sand and it took days to clear. I am now setting up a 400 gallon tank with a sump water flow of 1800 gal/hr and a closed loop in the tank of 1800 gal/hr with 8 returns. I was worried my tank may look cloudy for many days or the sand would blow around. It came moist with an additive which cleared the water. The next day the water was clear and the sand stayed in place. IMPRESSED!
Best sand on market. By Dirt Frog on 6/27/2016Dirt Frog would recommend this product to a friendI use this sand in my 125 gallon tank. Much better than the fine/sugar grain that. BRS does not bag items containing liquid so if there is a puncture of any kind during transport it gets messy. Had a bag of this sand shipped with other items and it leaked salt water all over everything. Customer service was notified and hopefully they adjust their packaging.
Poorly packaged. By New Fisher77 on 4/18/2016New Fisher77 would recommend this product to a friendSand looks good and showed up wet but clearly a lot of moisture seeped out during shipping as the box it came in was soaked.
Ask a question
Both Sands will work great for a Goby! Technically the Fiji Pink is slightly smaller grains. Both will be fine with the gobies gills. Feel free to let us know if you have any further questions!
The live sand contains dormant bacteria and can last a very long time, 6-12 months typically in storage at room temperature. It can even in some cases last longer. Feel free to let us know if you have any further questions!
You will need between 40 lbs (for 1" sand bed) to 60 lbs for 2" sand bed. Feel free to let us know if you have any further questions!
For a 1" sand bed you will technically need 122lbs. Feel free to let us know if you have any further questions!
It depends on the exact dimensions of your tank, but assuming a standard sized 180g tank your looking at right around 100lbs.
