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 Fiji Pink 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.

Good fine sand By Kirti on 8/2/2017Kirti would recommend this product to a friendThis sand is a small grain size and that is what I was expecting. It works great and the water was clear within 24 hours. I like the small packet which comes inside which helps with the water clarity. I definitely would recommend this sand if you are looking for fine sand.
Caribsea Fiji... By JcSH2o on 5/27/2017JcSH2o would recommend this product to a friendI bought this sand to mix with my African sand. It's a good sand, though I do recommend heavy rinsing if adding to an established tank.
Pretty uniform grain size, and easy to clean. Definitely not pink, so don't expect it to be. A light tan with barely noticeable pink flecks.
I would recommend, and I would purchase again.
Very Good Sand (Pink is Misleading) By Sean on 1/4/2017Sean would recommend this product to a friendThis sand is a small grain size but works well with good flow if you set your exceptions correctly. If you dump this in a new tank and expect clear water and it to settle inside one week and start adding corals you are in the wrong hobby. Slow and steady wins the race.I use MP10 and MP40s with it and no issues after a few weeks. Yes any pump will agitate any sand in the short term. But, after it settles it is fine. Also, it's not pink so if you think you are getting pink sand don't buy. It has flecks of colors that are nice and natural.
Good product By Willie b on 12/9/2016Willie b would recommend this product to a friendI was very happy with my purchase and you can see the pink chips in the sand, perfect for my seahorse tank
Excellent Shipping and Product By Steelsoul on 8/15/2016Steelsoul wouldn't recommend this product to a friendThe pink bits in this sand are only noticeable in the bags once in the tank you don't see um at all. This is a very fine sand and using 2 Hydor Koralia powerheads 1950 gph each move this sand into piles in the tank. If your like me and have high turbulence powerheads do yourself a favor and add a Large grain sand like the arag alive Florida Crushed coral along with this Fiji fine grain sand to keep your sand in place. Shipping was excellent, heavy but very fast.
Perfection! By JBrown on 5/26/2016JBrown would recommend this product to a friendFast and accurate service! That's number 1!
As for the Fiji pink, I got it because I was looking for a tan sand to mix with some African Cichlid sand I had purchased prior. It was a salt and pepper mix, and I wanted to tone it down some. This sand blended perfectly as the grain size was a perfect match.
It's definitely not pink, it is tan. It lightens up even more under tank lighting. Very uniform, and settles quickly. I should add that since this was going in a Malawi tank, I did lightly rinse the sand before mixing.
I really couldn't be happier. Great product for my needs.
It's Sand By William on 4/29/2016William would recommend this product to a friendI really can't tell if there are any of the little pink sparkly things in there, it looks like basic live sand to me. It is a really fine sand, not recommended for super high flow, turbulent, tidal, monsoon, type areas. I am pleased with it, but I am easy to please.
Looks great By Eric Johnson on 4/4/2016Eric Johnson would recommend this product to a friendThis works really well for me. It's fine but doesn't blow around badly unless there's strong direct flow. It is mostly white under my Kessil lights moreso than pink and I like it. Clears very quickly with the packet and didn't seem to affect any of my coral or inverts (I was adding to an existing tank).
It's sand By Samuel on 3/8/2016Samuel would recommend this product to a friendPersonally chose this sand because Brs recommended it. It looks like sand and feels like sand. I could tell it had pink sparkles in the bag but it just looks like white sand in the tank to me. I used a Brs 2 inch pipe to add the 10 lbs on top of my existing Fiji pink sand.
Beautiful and helps the cycle By James on 2/21/2016James would recommend this product to a friendI was nervous buying this sand because i was not sure how pink it would be. But the sand is white and it looks like it has pink crystals in it to liven it up and add some contrast. It took only a day to settle and my watchman goby seems to enjoy it. The super fine dust in the sand did leave a film over most everything in the tank, but it scraped off with good ease.
Looks nice By ERIC on 2/20/2016ERIC would recommend this product to a friendThe sand looks great in the tank but even slight agitation causes it to cloud the tank water. Maybe ringing the sand prior to adding it to the tank would help, but that would also probable eliminate the bacterial population in the bag. I will probably go dry next time.
Excellent buy By Samuel on 1/6/2016Samuel would recommend this product to a friendI can see why brs recommends this. It looks good in my new tank!
Ask a question
It depends on how deep of a sand bed that you are looking for. Assuming your tank is a standard 55g dimensions you can expect roughly a 1" sand bed for each 35lbs of sand that you use though.
It certainly can be added without much of a new cycle. You will ideally want to rinse the sand beforehand in tank water to removed the dust and fines when placing in the new sand. Feel free to let us know if you have any further questions.
For a 1" sand bed you will need 25 lbs. for a 2" sand bed you can double the amount to 50 lbs. Feel free to let us know if you have any further questions!
The Fiji Pink is not shipped with "ocean" water, rather it is dormant bacteria and saltwater and does not contain hitchhikers or other pests. Feel free to let us know if you have any further questions!
unfortunately I was unable to find the length of the tank provided. If you tank is 72" long and 24" front to back you will need around 100 lbs for 1.5" deep sand bed across the tank. Feel free to let us know if you have any further questions!
The clarifier is included is reef safe and may make your skimmer start acting up if it is running. Feel free to let us know if you have any further questions!
100lbs should be plenty for a nice 2" or so sandbed in that size tank. When it comes to aquascaping I always put the rock down first. That way you don't have to worry about a critter digging the sand out under the rock and causing a land slide or anything.
Unfortunately bringing in heavy items such as sand does take some time and accounting. I have submitted the request to look into bringing in more options such as Tropic Eden. Feel free to let us know if you have any further questions!
How deep of a sandbed is largely dependent on your own aesthetic preference unless you happen to have a critter that requires a certain amount of sand (like a Jawfish for example). For a tank that size you will get about an inch of sand for every 50lbs which would be plenty if you don't have any critters that require more.
Right about 70lbs of sand would get you about 2" of sand bed on a footprint that size.
It has the beneficial bacteria in it which is what makes it "alive" but it will still be pest free. Adding 1" of sand to a 27x72 area would require right about 100lbs of sand.
Assuming standard 2ft x 4ft dimensions of most 120g tanks. 120lbs would get you about a 2" sand bed which is pretty typical for most folks.
It wouldn't be a problem at all to use this with an existing tank. The biggest concern would be to make sure you remove the old substrate a little bit at a time. You don't want to remove it all at once as there may be a high population of your bacterial filtration on it.
That wont be any problem at all :-)
