Answer 2

Answer:

The assertion that an aquarium needs regular cleaning because there are no microbes to clean water in the aquarium is correct.

Unlike ponds and lakes, which are natural ecosystems containing decomposers that act as cleansing agents, an aquarium is an artificial ecosystem that does not contain decomposers to cleanse it.

Therefore, regular cleaning of the aquarium is necessary to maintain a healthy environment for the aquatic life living in it.

Over time, uneaten food, fish waste, and other debris accumulate in the aquarium and can cause harmful bacteria to grow.

If left uncleaned, this can lead to poor water quality and health problems for the fish and other aquatic organisms living in the aquarium.

Regular cleaning of the aquarium involves removing uneaten food, fish waste, and other debris from the bottom of the tank using a siphon or gravel vacuum.

The filter should also be cleaned regularly to remove any buildup of debris that may have accumulated on it.

It is recommended to change 10-15% of the water in the aquarium every week or two weeks depending on how many fish are present[1].

This helps to dilute any harmful substances that may have accumulated in the water. By maintaining a clean environment for your aquatic pets, you can help ensure their health and longevity.
