Benefits of Live Sand

Benifits of Live Sand

The number one reason most people use live sand is so they can jump-start their reef tanks cycle. By using live sand you are adding billions of microorganisms that will immediately start consuming ammonia from the water. That means you can add fish and coral sooner instead of waiting up to a month for an old-fashioned cycle.

Live sand also has a diverse range of microorganisms that can sometimes only be found in nature. These bacteria can be more efficient at processing waste than the bacteria that colonize your tank from your local environment.

Since live sand is basically ready right out of the bag, that means you can slowly start adding fish and coral as soon as possible. Of course, you should always test your water before adding any fish or coral to your tank to make sure your ammonia levels are acceptable.

Even though live sand can help speed up the cycling process it can still take a little time to get established. A good rule of thumb when you start a tank with live sand is that you should only add 1 inch of fish for every gallon of water. Once your tank is established you can increase that amount but you should always be careful not to disturb your reef tanks balance.

 

 

 

Adding Live Sand to an Aquarium

 

Mixing Live Sand with Regular Sand

There are a couple of things you need to consider before you add live sand to your reef tank. One thing you need to be aware of is that live sand is a little more expensive than regular saltwater aquarium sand or gravel. If you want to save a little money you can mix live sand with regular sand and still get the benefits of adding live sand to your aquarium.

 

How Much Live Sand

One question that commonly crops up is how many pounds of live sand will I need for my aquarium. While there is no single right answer a good rule of thumb is that you will need 1 pound of live sand for each gallon of water. This will be enough to create a nice even 1 to 2-inch layer of sand in most reef tanks. Although, if you want a deeper sand bed you can get 1.5 to 2 pounds of sand per gallon.

 

Water Cloudiness

One thing you might notice when you add live sand to your new reef tank is that the water will be very cloudy. This is completely normal, and in most cases, the particles will settle in a few hours. Some finer grain sand might take up to a day to settle though, so you should leave the tank overnight before you turn on any pumps or filters.

Certain fine grain varieties of Carib Sea live sand also comes with a packet of water clarifier, which can be added to your tank to speed up the settling process. If you prefer not to use a water clarifier you can rinse the sand in dechlorinated water. This will help remove some of the smaller particles before you add the sand to your aquarium. This is also a good idea if you are adding live sand to an already stocked tank since it will help protect your fish from any sand floating around in the water.
