The first and crucial step in cleaning the pebbles for any method other than the vacuum is to relocate your aquatic animals safely. You want to make sure your fishes don’t get harmed in any way during this process, so follow the steps accordingly.

  1. Ready another tank or bucket for the fishes. Ensure the container is completely clean and sterile, with no traces of any chemicals, cleaners, detergents, etc.

  3. Now, you can transfer your fishes into the container. The easiest way is by using a net; however, fishes with flowy fins and or tails can get trapped in them, causing them harm, so for them, you need to use your hands to transfer.

This method is the most commonly used for cleaning the gravels. It requires quite some effort, but it’s also the most effective way. You will get the most benefits from it if there’s a growth of algae in your aquarium.

  2. Now, take the remaining ones and put them in a sieve. Rinse them thoroughly under clean water a couple of times until they’re completely clean. You can wear a rubber glove while cleaning if desired.
  3. Ensure that the sieve and gloves don’t contain any chemicals before cleaning for reasons mentioned before.
  4. Once clean, you can transfer the pebbles back to the tank and the unclean ones in the cups. Mix them in the tank, and you’re ready to move back your fishes to their clean home.

If you have any aquatic plants growing in your aquarium or have a smaller tank that gets dirty easily, this is a great method that doesn’t require taking anything out. Although it’s not as thorough as the first method, it’s simple and does the job very quickly.

  1. Relocate your fishes and remove or unplug the air pump, filter, heater, and any other ornaments around your aquarium.
  2. Use your hands to incorporate the gravels very thoroughly. You can slide the pebbles around the plants in case you’re worried the stirring will harm them. It will cause the trapped debris and detritus to come out, making it easy to remove them.
  3. Next, take out around 50% to 30% of the tank water from the top. You will need to keep some of that dirty water as it contains those beneficial bacteria.
  4. Refill the tank with clean water and place your fishes and ornaments back in its place.

An effective way to keep your fish tank pebbles free of any debris and waste is to add friends to help keep them clean. However, you have to be very sure of yourself before getting one of these creatures as it’s one another animal to take care of.

  1. When going for algae-eating fishes, contemplate whether they will get preyed on by the other fishes or not. Like, even though Cherry shrimp is an excellent creature that feeds on the detritus, any bigger fishes will, however, eat them up.
  2. Having detritivores is another great way. These animals eat organic matters and proteins that you can usually find with gravels. One of which is the Malaysian trumpet snail. They also oxygenate the plant roots.
  3. Another great one is the Siamese algae eater. They not only eat algae and all the detritus in the pebbles but also flatworms as well. Thus, it helps keep the water fresh and sterile.

How Often Should You Clean Your Fish Tank Gravels?

Accordingly, having a larger tank means it will take more time than a small one to collect detritus, especially if you have plants growing. For such aquariums, it’s best to clean the pebbles once every two weeks.

But generally speaking, cleaning them every two weeks is ideal for every fish tank. You can also take out and change around 10% to 20% of the water every week for measures.

Is It Really Necessary To Keep Them Clean Often?

You can skip cleaning gravels often by having a fully cycled tank. It will help disintegrate ammonia and nitrites from fish wastes. However, if left like that for long, it will cause algae to grow. To make it worse, it will eventually also create too much anaerobic bacteria, giving off a rotten egg stench.

Moreover, it will cause the water inside to get dirty faster, so you will have to change the water more often than normal. Due to this, it’s better to at least clean or vacuuming the food particles and plant matter to avoid all the trouble.
