What Types of Aquarium Filter is Best for my Tank?

Though there are many different types of aquarium filter made available in the fish stores but it boils down to…

Two different kinds of Aquarium filter

• Internal aquarium filter
• External filtration systems

Internal filters are used in saltwater and fresh water aquariums. Many saltwater aquariums have an internal tube for the water to flow down into a sump tank, which is just below the main tank and all the water passes through a certain type of foam where all the waste and bad bacteria gather and this filters the water. The water is then pumped back up to the top of the main tank and this flow continues on constantly.

Although a noisy method, it is the second most effective aquarium filter but rather pricey.

The other way of doing internal filtering is to have what looks like a large black rectangle stuck to the inside of your tank, this sucks up water and waste through its bottom, the water then passes up through the filter. This method is the third most effective method and is very cheap.

The external filter is the way to go, this aquarium filter is a hard working piece of machinery that keeps your aquarium in tip top condition and gets rid of all the water. It is like the other two methods of internal filtering above but it is all done outside of the tank. The only thing connecting from the tank to the filter is a long black tube. This is the most effective and expensive way to filter your tank but it is very worth it.

All these types of aquarium filter are available at your local fish shop or any online fish store, but not really your local pet shop. For the internal filter that requires a sump tank, this is usually custom made to suit your tank so it is expensive but not really worth the money, in my humble opinion. You are probably better off choosing an external aquarium filter, although it will cost you slightly more, but it is far more effective and it creates less noise – that’s if you want good night sleep.
