Fish tank management such as cleaning the dirty fish tank is sometimes necessary; however, you should try as much as possible to avoid cleaning the tank since you will lose the beneficial microbes from the pond.  Only clean the best fish tank filters if it is in an extremely bad state. With simple items like elbow grease, you can easily clean your pond. Several steps are followed in cleaning a fish tank.

Clean the inside of the glass

Start by scrubbing on the inside of the glass using an algae pad. Use special algae pad for cleaning fish tanks and never use the home pads since they may contain detergents that can be harmful to your fish. Use a razor to scratch hard stains.

Clean the decorations and the rocks

Remove all the rocks, plants and decorations inside the pond and clean them. Do not use soap because it will be hard if it enters hidden places. The soap will potentially harm your fish. Use the algae scrub to remove the dirt as well as any dirt. You can prepare bleach and soak your items; however, you should be careful with plants since some plants can be destroyed. Rinse properly and air dry before returning them to the pool; however, you should carryout siphon cleaning of the gravels before putting them back.

Carry out siphoning to clean the tank gravel

Clean the tank using a siphon to remove debris. Carry out proper siphoning, especially on the surface of the gravels to ensure that all the debris is removed.

Clean the outside and other fixtures

Once the inside of the tank is properly cleaned, it will be time to clean the outside. You should clean the hood, inside of the glass, tank top, and the light. Avoid using the normal glass cleaners since they contain ammonia that could be poisonous to the fish. You can use vinegar or special cleaners designed for fish tank glass.

Clean the filters after two weeks

Once you have cleaned all the other areas, wait for two weeks before cleaning the filter. This is because there are beneficial bacteria that habit the filter and cleaning the filter will completely eliminate them from the tank ecosystem. Waiting for two weeks will allow reestablishment to the ecosystem. You should also change the media if it has stayed for more than one month.

Engage in continuous maintenance

Once your tank is clean, start engaging in regular cleaning to maintain your tank and avoid problems that will result in a major cleaning again. Clean the glass at least once per week, perform vacuum cleaning and regularly change the water. Change the filters at least once per month.


It is not easy to clean a fish tank but if it is dirty, you will not have any choice other than to clean the pool. Always follow the above steps to ensure the safety of your fish. Once the pool is clean, maintain the clean state to avoid future problems.
