Mechanical Filtration Removes Particles
The whole idea of mechanical filtration is to remove unwanted particles from the water. The fish excretes in the water. Uneaten food also remains in the water.

It filters the larger particles first, and another layer gets rid of the finer particles.

The ammonia in water can easily kill your pet fish since it’s highly toxic. Since your mechanical filtration system might not filter fecal matter and leftover in time, they could produce ammonia in the fish tank. The ammonia in the water, the mechanical filters convert the ammonia into nitrogen, which is less harmful.
Keeps Your Water Clear
Chemical filtration for canister filters usually comes in the form of activated carbon. The carbon removes water impurities such as chlorine, especially if you’re getting water directly from your faucet. Basically, the activated carbon eliminates discolorants, and the water becomes crystal clear. If you choose to include a chemical filtration in your filter setup, it improves the aquarium’s water quality.
