One of the most sensitive devices you will ever have to purchase when you are setting up your fish tank is the filter. With hundreds of filters available on the market, sorting through them all to find the best filter for fish tanks can be challenging. Both saltwater and freshwater fish need at least three levels of proper filtration to live long, healthy lives. In the guide section below, we discuss what makes a great filter, and what features you should and for when purchasing a fish tank filter

Guide to Purchasing the Right Fish Tanks Filter

There are quite a few styles, options, styles, and features to think about when buying an aquarium filter. The first thing you have to consider is the style of aquarium filter you want for your fish tanks.

Types of Aquarium Filters

 Submersible Filters

These are the most common type of filters. They come with a suction cup or some kind of clip and are easy to attach to the aquarium wall and have a powerhead that provides filtration, and they allow water to flow through them, thus filtering them in the process.  They perform mechanical, chemical, and bacterial filtration perfectly.

Hang on Filter

They are attached to the side of an open tank and can aerate their own water flow themselves. They are able to perform the three stages of filtration perfectly, and they come with different flow capacities.

Canister Filter

Canisters filters allow users to swap out the various filtration material that makes up the filtration process, and they last longer than most types of filters. They are also more expensive and provide a powerful flow.

 Gallons per Hours, Filter Sizes, and Three-stage Filtration

Gallons per hour represents the volume of water your filter can purify or clean and aerate within an hour. This typically means that you will need to use the device less, thus causing less noise and consuming less power.

Filter Sizes

Filters come in different sizes and are typically measured by the volume of water they can comfortably filter before becoming ineffective altogether. This number typically ranges from 10-70 gallons or more.

Three-stage or Step Filtration

This term denotes the mechanical filtration (involves removing debris), chemical filtration (removes odor), and bacterial or biochemical filtration (removing nitrite and ammonia) process every good filter has. This three processes clean the debris and purify the water. Typically, you want the device you choose to be capable of all three levels of filtration, but just the bacterial, and the mechanical is fine also. We recommend always choosing a filter capable of all three levels.
