How To Clean Old Aquarium Gravel In The Three Simplest Ways
The gravel in your aquarium needs to be cleaned at least once every two weeks. The most basic rule is to clean it with each change of water. Now it’s time to say a little more about the process itself.
How To Clean Old Aquarium Gravel With A Vacuum

Bucket of water
Freshwater with dechlorination liquid
Disconnect all electrical equipment from the aquarium. Since the process doesn’t take long, you don’t have to worry about durability and the removal of water, fish or aquatic plants, and aquarium decorations.
Place the bucket below the level of the aquarium and immerse the suction kit in the water. Note that the suction pipe of the siphon should be completely inside the tank.
Cover one end of the tube with your thumb and immerse it in the bucket. The other end should lie under the gravel base. When you have finished setup, release your thumbs. By this act, the old dirty water with debris and waste along the pipe will go directly into the bucket. The procedure is complete when clean water starts coming out of the tube.
Pay special attention to the dirtiest parts of the aquarium (cracks, boulders, rocks, and caves). When it comes to aquatic plants, try not to get closer than 2 inches, because they actually feed on organic waste.
You can complete the suction process when the water level drops by about one-third of its full height. Simply cover the ends with your thumbs again and remove the tube from the tank. Keep in mind that it is not good to clean the whole tank at once, as it is not good for fish and plants either.

Put the gravel in a bowl and pour a mixture of water and bleach into it. Be careful not to soak it for more than 15 minutes as the material may break due to a chemical reaction. Rinse it several times with warm water and air dry.
Cleaning Gravel And Fish Tank With Vinegar
Vinegar is the safest natural way to clean an aquarium without adversely affecting the fish and the things in it. You can use apple cider vinegar or white distilled vinegar. It’s best to make a mixture of vinegar and water in a ratio of 1: 1. You can even soak the filter, heater, hose, pump, gravel, and decorate things with vinegar.
