Better movement helps spread out heat, oxygen, and food in the tank, which is good for your fish, plants, and other living things. It also stops places where dirt can gather in the tank.

When you over-filter, you might remove important nutrients and helpful tiny organisms from the water, messing up the balance in the aquarium. It’s important to find a good balance between keeping the water clean and keeping the environment natural and stable for your fish and other aquatic creatures.
