Top 6 Best Sand for Your Reef Tank
Best Sand for Reef Tank Reviews
One of the best things about this Fiji Pink sand from CaribSea is that it is packed with millions of good bacteria before you even put it in an aquarium.
There are heterotrophic, autotrophic and chemilithotrophic bacteria that help reduce waste and shorten the cycle time generally required when installing a new tank.
In fact, it is specially designed to avoid all the problems that arise with a new tank and acts as a nitrate filter, ammonia reducer and biological filter in one.
It is beautiful enough to use alone, but you can also use it with another substrate to quickly add beneficial bacteria to the aquarium. A water purifier is included to quickly clean the water when it first enters the tank. It is also specially made to maintain the growth of bacterial colonies.
Ideal for large colonies to attach to, the surface contains a source of calcium, carbonate and trace elements to balance pH without adding additional chemicals.
One more thing, this substrate never needs to be replaced. It works with the natural bacteria in the aquarium to keep your reef happy and healthy.
CaribSea uses a cold preservation process with this Ocean Direct substrate. Each grain of sand is covered in bacteria that came straight from the ocean when it was collected.
It is encased with a thin film of ocean water that remains open to the air so that gas exchange can continue. This allows beneficial bacteria to continue to grow without harmful buildup.
This aragonite sand from the Caribbean Sea is a perfect natural substrate for reef aquariums. Provides a natural balance of bacteria and minerals needed to maintain water balance.
Because it is reef sand, it is specially formulated to create a reef-friendly environment. It comes from real ocean water, not shallow reefs or beaches.
Believe it or not, this sand keeps the pH at 8.2 without constantly adding chemicals to the water.
That’s not all.
For every pound of this sand, there is 10,000 square inches of surface for beneficial bacteria to grow. This provides a natural way to control nitrate, ammonia and other harmful waste.
Nature’s Ocean produces high-quality sand that is completely natural. It actually comes from the ocean and contains live marine bacteria that have stabilized your tank very quickly. The process they use preserves all bacteria in their natural state so they quickly adapt to your aquarium.
In fact, you can set everything up and put your coral and all the fish in the tank on the same day. The instant cycle quickly restores the natural balance of the tank water, removing ammonia and nitrate quickly and effectively.
This sand contains live aragonite that helps control nitrate levels and maintain a good pH. There are also many natural living beneficial bacteria on this substrate including heterotrophs, autotrophs and chemolithotrophs to give a perfect balance to the water.
The sand also provides a large surface area for colonies of beneficial bacteria to continue to grow and thrive, creating a welcoming environment for your reef.
Another Caribbean Sea winner, this live black aragonite sand does a great job of highlighting the colorful coral in your tank. Like other branded products, it contains millions of beneficial bacteria to aid in biological filtration, resulting in an ideal environment for tetras, angelfish, cichlids, and even turtles, but it works just as well in a reef tank. The company’s trademarked Arag-Alive substrate also promotes coral growth, which is high in calcium, strontium and carbonate, and helps remove nitrates from the environment. Available in a 20lb bag, the sand contains a biomagnetic clarifier to reduce turbidity when placed in your tank.
Customers write that this sand is about 80% black, with some white and red sand mixed in. In other words, it’s dark enough for your tank’s colors to come out. The consistency is heavier than several other variants, but not like gravel; buyers liken it to the texture of sugar candy, which prevents it from flying off the bottom of the tank. If you’re looking for live sand that makes a strong visual statement, this is a solid option.
Why use coarse sand? For example, the larger grain size reduces the build-up of debris in your tank, and some critters (such as certain crustaceans) will appreciate the ability to dig and build. We recommend the coarse reef sand of Two Little Fishies, which consists of white aragonite, calcified algae flakes and even small coral skeletons. It’s also packed with the company’s BioPronto live microbes, giving you the same kind of biological filtration found in most other live sand products.
Two Little Fishies Live Coarse Reef Sand does not require rinsing and any cloudiness in your tank should clear after a few hours. The granules have an average size of three millimeters, large enough not to be thrown around your tank. It comes with natural seawater and is sold in 15lb bags.

Also, the pH is balanced without adding chemicals. This substrate looks great and as a bonus it never needs to be replaced.
How Much Sand Do You Need for a Reef Tank?
The depth of your sand bed is an important consideration when setting up a reef tank and you don’t want to get more or less sand than you need. So how do you find out what the right amount is?
How to calculate the amount of sand per gallon?
To know exactly how much sand you need in your tank, you need to know the depth of the sand bed you want to create and the dimensions of the tank bottom.
But there is an easier way to get an approximation by just using the tank volume. The volume of your tank in gallons is approximately equal to the amount of sand in pounds it takes to make a 1 inch bed. So if you have a 10-gallon tank, 10 pounds of dry sand is enough for an inch bed.
shallow vs. Deep sand beds
There is much debate in the aquarist community as to whether a shallow bed, between Â¼” and 2″, or a deep bed, between 3 Â½” and 6″ or more, is better.
Shallow sand beds remain oxygenated at all times, so to avoid nitrogen buildup that could alter the chemistry of the water in your tank, you should siphon the bed about once a month.
On the other hand, deep beds do not have oxygen at the bottom of the bed, which allows bacteria to facilitate denitrification so that the nitrogen balance in the tank is self-correcting.
Therefore, deep beds require little or no maintenance and can even be damaged by intensive cleaning.
In general, avoid sand beds between 2â€ and 3 Â½â€; Beds at this depth will allow toxic chemicals like hydrogen sulfide to build up and back up into the tank water, which can be quite harmful to your aquarium.
How to Keep Your Sand Clean in a Reef Tank?
Reef sand is very different from most other substrates. You really don’t have to change it often. Instead, it’s ideal to add a few animals to your reef tank to turn over the live sand. These creatures are affectionately called janitors, keepers, or cleaners. Some good options are hermit crabs, shrimp, gobies, or jaw fish.
Be sure to research these creatures before putting them in your tank, as they can’t all live together in peace. If you get the right mix of janitors, you won’t have to clean the sand thoroughly.
That said, it’s still important to maintain a clean surface. Use an aquarium vacuum cleaner or siphon to clean up any food or debris. Make sure you also get everything that is hidden between stones or plants.
A reef tank requires a perfectly balanced tank that can be difficult to get to. That’s why it’s important to use the right sand as a substrate when building your tank environment. We looked at several great options, all natural sand collected from the ocean floor with its colonies of beneficial bacteria intact.

Add some janitors to the tank and they will do the job of removing the sand for you. All you need to do is use an aquarium vacuum or siphon to remove debris from the sand surface if necessary. That is! Without changing or washing the substrate, without rotating water.
