Should my fish tank filter be loud?
There are many reasons why it usually happens. But the primary reason is when the filter gets dirty, especially in the filter media. The fish tank filter will also be noisy if some parts are broken, making it not work efficiently. A high flow rate and low water level can also make the fish tank filter loud.
Why is my fish tank air pump so loud?
