    For cleaning the decorations, take a bucket that does not include any sign of soap or detergent. Soap is not suitable for fish. That is why, to stay on the safe side, cleaning experts recommend using a bucket that you use only for fish tank cleaning purposes.

    Soak the Decorations: Next step is to clean the inside plants, decorations, stone statues, etc. If they are not too dirty, you can skip this part. But if they are dirty enough, soak them in bleach liquid for 15 minutes. Now, the question is, how much percentage of bleach is ideal for the job?

    According to the experts, a 10% bleach solution is best. It will clean even the stubborn dirt from the decorative pieces. Scrub them well. Then, rinse in the running water. Once they are clean, the air dries well. Thus, the residual bleach will go away.

    Make sure they do not emit any chlorine smell. Wash well as much as it requires. You can use sodium thiosulfate in the water to remove the chlorine from them. For live plants, prepare a 5% bleach solution to soak them into it for two or three minutes. Do not use bleach for stem plants.

    Leave the decorations artificial and live plants outside the tank until you clean the gravel. When you clean the gravel, many a time, the debris coming out of gravel can settle on the decorations. You may have to clean them again. Keeping them aside in a bucket reduces your hassles of extra cleaning.

    Clean Gravels using Siphons: When you learn how to clean a fish tank, you should clean the gravels. Gravels get covered by sticky dirt most of the time. Use a high-quality water siphon to remove the dirt. The siphon helps to clean the gravel by vacuuming the dirt. Run the vacuum cleaner across the surface. All debris will be cleaned.

    Well, when the vacuum replaces the water, it is dechlorinated. Make sure the temperature of replaced water is the same as the remaining water inside.
