It makes a cloudy mess to add any sand to an existing tank (which is just an inconvenience more then an actual issue) but it shouldn't cause any sort of cycle. Live sand isn't like live rock in the sense of it having critters in it (that could die, cycle, etc) it just has bacteria on it.
The ideal sand bed will vary from tank to tank whichever you prefer! For 1-1.5" sand bed you will need 70 lbs of sand for a tank of your size. Feel free to let us know if you have any further questions!
Caribsea's Ocean Direct Caribbean Live Sand is a great choice for aquarists who are wanting a reef tank set up in minutes.
Available in various shades and sizes:
- Original Grade - 0.25-6.5mm
- Oolite - 0.25-1mm
Great buy By Aimie on 1/12/2016Aimie would recommend this product to a friendI grabbed this to help weigh my finer grain sand in hot areas where the sand shifted easily. I was easily able to mix this in with the places that needed a little more weight with no issues of making it look natural. Truth is, it made it look more natural having the few spots of heavier grain variance. The bag came with the bacteria to add after the fact and it is a critical point to use. It helps to weigh the suspended stuff clouding the tank so it drops more quickly. I added it even though I didn't end up with a huge sand storm even without rinsing the sand. I also saw no major fluctuations when I added this. I didn't add the whole bag to my 150 gallon, but there was a decent amount used and expected a small spike but none came. The packaging from BRS was a million times better for this sand in comparison to the other online place I bought my first batch of sand (which also sent the wrong sand and started the need for this purchase). I have only positive things to say about the packaging BRS provides for their goods! A+ service and A+ product!
good looking sand By carl on 12/26/2015carl would recommend this product to a friendI purchased a 40lb. bag and made the mistake of just dumping it right into my new tank setup. Was cloudy for a week. Once it cleared, the sand looked great. Bought a second 40lb. bag and pre-washed it in new saltwater. cleared up after a day. Am really happy with the end result.
There is a lot of junk in it By John on 12/22/2015John wouldn't recommend this product to a friendThis sand likes fine but when you put it in oar tank there is a lot of junk in it stones, big shells 3”to4” in size. Brown in color like play sand. I would not recommend this to a friend

No Problems By Brett on 8/20/2015Brett would recommend this product to a friendThis is my second experience with this sand. Never had any problems with any water quality.
Great Sand, Very Natural Lookin By Garrett on 6/30/2015Garrett would recommend this product to a friendI was originally hesitant to buy this sand due to the large variety of grain size, presence of shells, and the possibility of sand storms in an SPS dominated tank. I am really glad I went with this sand because of they very natural looking mixture of sizes and shells. This sand gives the feel of the actually variety you would see when diving. Small grain size is no problem with 2 alternating Gyre 150s and the shells/debris that you don't like can be picked. out.
Great sand but lots of big items By Josh on 12/18/2014Josh would recommend this product to a friendI have to say that I am pleased with the sand. I purchased 60lbs. for my 60 gallon SSB, and ended up using less thank 40. I guess the rocks directly on the glass took up a lot of surface area. I placed the sand in then filled the tank by placing a glass bowl at the bottom and filling that up and letting it flow over. I did not rinse the sand first, and I have to say that I am impressed with the cloudiness, as it was not bad at all. The only con is that there were a ton of chunks, shells, ect in the rock.
Excellent By Roger on 11/20/2014Roger would recommend this product to a friendI've used this sand for almost a year now. Liked it so much I bought some more last month for a tank upgrade. Nice color and size.
dependable By b-christopher on 10/5/2014b-christopher would recommend this product to a friendI have used this product for some time and have never been disappointed. My order from BRS was no exception.
Great prices. Safe, secure and speedy shipping as usual.
Very good substrate if you know what you're doing By Brad on 9/11/2014Brad would recommend this product to a friendFelt like I should add this review after seeing the 1-star review. When you add sand into an established aquarium, NEVER add all of it at once. The new sand will smother the existing life on the top 1" of your current sand bed and cause those organisms to die. This creates hydrogen sulfide spots in your sand if it is deep enough, and is most likely what will cause your aquarium to crash.
If adding to a new aquarium, just give it time for the dust to settle and you should be fine. I have never had any issues with CaribSea and have only ever had positive experiences using their products.
Great sand By Richard on 9/1/2014Richard would recommend this product to a friendI love the look of this sand. I have heard complaints about cloudy water because this sand is so fine. I had that problem at first. It took about two days for the sand to settle down and the water to clear. I did a second tank, but this time I put the water in at a slow rate. While the tank was a bit cloudy at first, within a couple hours it was clear. I would recommend this sand.
Do not freak out when you first add this sand By Joey on 12/6/2013Joey would recommend this product to a friendI needed to add more sand into my tank after regular sand maintenance and bought this sand when I saw the good review.
This sand is roughly 4x finer than caribsea Fiji grade which was the sand I had before. It contains random shells & some pieces of wood (I really do not know how those wood got in them).
I immediately went to put the sand into my aquarium after I got it, no rinsing what so ever. The tank went crazy, it became a milk tank! There were foamy layers EVERYWHERE.
I really panicked for a little bit, here is what I did to make the water CRYSTAL clear in 2 and half hours:
I turned my skimmer to wet skim and put a bucket underneath it, the skimmer will go crazy once you put the sand in, it literally collected 2 gallons of muck in that time frame.
I then added extra layers of filter socks + filter sheet on both the sump and the over flow, then I turned my vortechs to full speed and left them at that.
Lastly, I added 2 bags of carbon.
The sand is beautifully white, I believe it looks much nicer than the Fiji pink sand, I love it after all the milky stuff cleared.
Last note, I recommend you suck those random pieces of wood out with a turkey baster, otherwise they'll keep on floating around your aquarium and never seem to settle, or get stuck onto your vortechs/overflow.
