So let’s start.

What is an Aquariums Filter

An aquarium filter is a product that will clean the physical and chemical wastes from the aquarium without harming the fish’s health. The aquarium filter will make your cleaning job easier and provide crystal-clear water without changing the water parameters.

The process of removing excess food, decaying organisms, and fish digestion waste from the aquariums. There are different types of filtration methods such as Chemical, Mechanical, and Biological.

Let’s look at each type.

Different Types of Filtration

There are three different filtration processes. 

Before that, If you’re looking for a canister for 20-gallon aquariums then do check my blog post for detailed reviews of the best canister filter for 20-gallon aquariums.

Biological Filtration

Biological Filtration is the process of reducing the toxic nitrites and ammonia from aquariums. When the fish waste and uneaten food waste break down into toxic ammonia, the filter will convert them into less toxic nitrates.

It will not harm the fish’s health, but if the ammonia gets start spreading and affecting the fishes, then there will be a chance of the sudden death of fishes.

So, for converting the toxic ammonia into nitrates, you can use biological filtration. 

Chemical Filtration

Chemical Filtration is the process of removing dissolved waste from aquariums. The main element for removing dissolved waste is using activated carbon.

The other chemical media will remove the dissolved organisms and chlorine and phosphate.

Many people are saying the chemical filter needs to be ON every time whereas others are saying, you can use chemical filtration when you see a sudden spreading of ammonia.

Mechanical Filtration

Mechanical filtration is the process of removing unwanted solid particles from aquariums.

The filter media will trap the decayed plant waste, uneaten food, and fish waste. Mechanical filtration was excellent for every fish tank because trapping solid waste requires a filter.

Otherwise, The water will become dirty and fish start to struggle to breathe oxygen. 

Now you have an idea about the filtration process.

Which type of Filter is Good for 75-gallon Aquariums

There are different types of filters available in the market.

Such as internal filters, hang-on filters, canister filters, etc.

You can choose the different types of filters according to your preference and the space available to you.

I will recommend using a canister filter for aquarium filtration because it was very easy to use and maintain. You can place it near the aquarium tank.

The performance was also improved in the canisters filter. External filters are more powerful than internal filters.
