How to clean the bottom of an aquarium without a vacuum cleaner?

How to clean the bottom of an aquarium without a gravel vacuum? Even if you change the water in your aquarium regularly, the bottom can still become dirty. The substrate, made up of sand and rocks, must be stirred to remove waste. Otherwise, the organic matter that accumulates there can poison your fish.

With a gravel vacuum, removing debris is easy. But what if you don't have this electric device? How can you clean the bottom of an aquarium without a gravel vacuum?

3 ways to clean the bottom of an aquarium without a gravel vacuum

Even if you don't have a gravel vacuum handy, you can clean the bottom of your aquarium with ease. Three simple tricks will allow you to achieve the same result as with an electric siphon.

1. Use a flexible hose;
2. Empty the tank completely to easily access the bottom;
3. Add animal species known for cleaning aquariums.

Let's take a closer look at these three techniques.

How to clean the bottom of an aquarium with a hose?

Before starting, get a flexible garden hose, a hose clamp, an empty plastic bottle, and a large bucket. Then, proceed as follows:

• Cut the plastic bottle 10 centimeters from the end to make a bell;
• Insert the bell's neck into the end of the hose (use a hose clamp to properly fit the diameters of the two parts);
• Place the free end of the hose in a bucket lower than the aquarium;
• Submerge the bell facing upwards in the aquarium water;
• Turn the bell towards the bottom once the hose is full of water;
• Stir the substrate with the bell, which will suck up the debris while avoiding the rocks;
• Remove the bell from the aquarium to stop the siphoning;
• Top up the aquarium using aged, dechlorinated tap water.

How to empty the aquarium completely to clean the bottom?

You can completely empty your aquarium using a garden hose. This allows you to easily access the substrate at the bottom. To do this, get a net, a bucket, a garden hose, two or three containers, and a soft brush. The containers will allow you to transfer the water from the aquarium.

For this method, proceed as follows:

• Dip one end of the hose, facing upwards, into the aquarium;
• Place the other end of the hose in a container on the floor, lower than the aquarium;
• Turn the end of the hose dipped in the aquarium towards the bottom;
• Let the water flow into the bucket;
• Remove the hose from the aquarium to stop the water from flowing;
• Place your fish in the bucket filled with water;
• Continue emptying the tank;
• Fill the containers with the water as it drains;
• Retrieve the stones, rocks, and roots and rinse them in a container of clean water;
• Put the decorations back in place;
• Carefully refill the tank using the containers of water;
• Gently add the fish back into the aquarium.

Which scavenger fish should you choose to clean the bottom of the aquarium?

The third solution for cleaning the bottom of the aquarium relies on scavenger fish. Some of the most effective include catfish, which feed on waste settled on the bottom. They live at the bottom of the aquarium and remove debris from every nook and cranny. Some mollusks, such as shrimp, are also highly prized by aquarium enthusiasts. Their activity in the sand removes all debris and makes an electric gravel vacuum unnecessary.
