Half Gravel Half Sand Aquarium – Simple Setup Guidelines

Preparation

Separating the sand and gravel is the initial thing you must do because many bottom-dwelling animals, including cormorants, adore sand and can become ill from eating it if it contains gravel. 

It would be ideal for placing a tiny divided stone in the center, or you could merely layer the gravel on top of the sand to make the contrast more obvious. 

You will also want to handle the sand and gravel separately when deciding which is suitable to put in your aquarium.

Create A Divide

Although some aquarists may think mixing sand and gravel is good and acceptable, do it with caution because, as we indicated before, sand-loving species can hurt themselves when feeding if they accidentally swallow small gravel.

For the best results, make sure the gravel layer is higher than the sand, so it will eventually fall into the sand and prevent too much mixing. 

Select The Gravel

Let’s begin with gravel, as you will need to choose the foundation first. 

It is advisable to use hexagonal gravel when blending two different substrates in a single tank. They are less difficult to keep than round or square forms, which do not leave excessive space between the particles. 

The hexagonal type is also smooth enough to encourage the development of beneficial bacteria in your aquarium while still being sufficient to allow for water flow.

Set-up The Gravel 

Once you have finished picking out the stones, let’s begin to set them up.

  • To ensure that you can do the next procedure properly, only pour 5 lbs of gravel into a big 5-gallon container.
  • Pour an inch of cold water into the container to cover the gravel, then stir around to rinse.
  • Give the gravel time (about 5 minutes) to soak in water to let the dust float upward.
  • Wash 5 lbs of gravel by draining the water and carrying out the same procedure three more times.
  • One pound of gravel should be removed from the container using a sieve, and you should rinse the water thoroughly until it is clean.
  • Purchase your preferred dechlorinating solution, wash the gravel following the directions on the container, and then give it a good rinse.
  • Repeat the steps above for the rest of the gravel you need
  • Fill the bottom of one of the tank’s sides with gravel until it is approximately half an inch thick.
  • To maintain the water’s great quality, wash the gravel twice per month using a siphon set.

Select The Sand

This is important as sand has a lot of benefits for your tank. 

Since some species prefer particular sand, picking your sand can be a little more challenging. 

If you are unclear about the variety of sand you need, it’s best to see a professional at your neighborhood fish store. They can help you to locate the ideal soft spot for each of your fish if you are raising many kinds. 

Besides, they can provide further insight into whether your specific fish will be safe in a tank that is filled with half gravel and half sand.

Set-up The Sand

What you should do is:

  • Choose the appropriate sand for your tank and fish after consulting an expert.
  • Before making a purchase, calculate how much you’ll need for the second half of the tank.
  • To adequately rinse it, add 7.5 quarts of sand to a 5-gallon bucket.
  • Fill the bucket with cold water so that the water is 2 inches above the sand. 
  • Once the bucket is full, use the hose to swish the sand to stir up any dirt.
  • Wait five minutes before you drain the filthy water.
  • Continue doing this until the water is crystal clear.
  • Once it is clean, take the sand out of the bucket and pour it into the tank’s bottom on the divider’s open side.
  • Use a vacuum cleaner to wash the sand twice per month, keeping it directly on the sand surface to avoid drawing the sand up.
