Question

What is the importance of aquarium filtration?​

Answer 1

Answer:

Mechanical filtration serves to remove free-floating waste before it decays into harmful substances, and to be beneficial the filter material must be cleaned or replaced every two to four weeks. In addition to filtering contaminants from the water, mechanical filtration assists in aerating the water.

Answer 2

Answer:

Here's your answer

A filter basically cleans the water of debris, removes the toxic buildup of ammonia and nitrates, and aerates the water so your fish can breathe. Which, unless you want an aquarium full of dead fish (or one filled with plastic fish), is a very good thing, indeed.
