Types of Aquarium Filters Available in the Market

There are several different aquarium filters available in the market to keep your fishes safe. Every filter has its good and bad points. However, you would like to remember the following factors to choose the right option to fulfill your requirements.

Air Driven or Sponge Filters:

There is some standard basic setup of a filter in the market. Filters don’t do much when it involves chemical, biological, and mechanical filtration. Air-driven filters are best for breeding tanks or a tank that has small fish. The sponge/air-driven filter works on a vacuum pump where the water pulls through the sponge material. The sponge itself is beneficial for surviving helpful bacteria in mechanical filtration.

Hang on Back Power Filters: 

The most common filter you’ll see is that the hang-on back power filters. They fit on your aquarium by hanging over the rear of your tank. They filter the water through a suction tube inside the aquarium and push the water through a filter pad. Most of those filters bring a filter pad that’s jammed with activated charcoal to get rid of harmful toxins from the water. Inside the filter, beneficial bacteria have a perfect area to grow. Therefore, you can add these bacteria to your water, making it a healthy and vital environment for your fishes. Some of the newer hang-on back power filters accompany a bio-wheel with a specialized biological filter.

Canister Filters:

Canister filters are often getting used by fish hobbyists. These filters are great that are 40 gallon fish tanks or large. These filters are among the simplest for mechanical, biological, and chemical filtration due to how large they’re compared to hold on back (HOB) power filters. 

Canister filters have a siphon tube and a versatile pipe that goes from the filter to the tank. The water goes up through the filter then spreads out back to the tank employing a water bar. It is the best filter for aquariums once you have cichlid, live plants, or large fishes. The filtration process is making for better mechanical filtration by forcing the water through a fine mesh. Biological filtration is completed through oxygen that’s skimming the water. 

Under Gravel Filters:

You can place gravel filters under your substrate. They pull water up through uplift tubes. There are two ways in which the water travels up through the under gravel filter. 

  1. One is by an air stone and vacuum pump that matches the highest tube and pumps the water around the tank. 
  2. The second is through a strong pump that sits on top and sucks the water up. 

You can get mechanical filtration when the water passes through gravel. However, biological filtration can only happen if the water is passing over the substrate. Chemical filtration doesn’t happen with this kind of filter.

Internal Filters:

These compact filters are great for Nano tanks, like 5 gallon tanks. They’re stuck to the within of the glass using suction cups. Most people use them by placing them at the rock bottom to stop dirt from building up. There are internal filters that possess a vacuum pump with an airline that’s connected to the filter. This connection will allow water to maneuver through the filter easily. The air bubbles pop up at the surface of the water, and you can get good mechanical, biological, and chemical filtration.

Wet/Dry Filters:

Experienced tank owners still employ Wet/Dry filters, although these are not as common as other filters. You are more likely to find them in saltwater tanks. These filters are great for biological filtration because being exposed to both water and air helps discover an outsized gathering of beneficial bacteria and eliminates waste. 

Dry filters are more rigid because you need a reservoir to carry water and assist the water run to the pump. Chemical filtration happens once you place a chemical media within the filter. However, mechanical filtration is extremely limited.

Fluidized Bed Filters:

A fluidized Bed filter will mount on the rear of your tank, and it pumps water into it. Then water will transport through a pile of granules. These granules can contain plastic, sand, or silica chips. It works similarly to a sand pool filter. Fluidized Strip Filters require that you purchase a pump separately to suck the water into the filter. Most of those filters don’t come with the pump. Biological filtration occurs when beneficial bacteria grow on the surface of particles that are suspended. Chemical filtration with this sort of unit isn’t ideal, and mechanical filtration is merely semi-good.

Basic Roles of the Filter

You might be wondering what role your aquarium filter plays in your aquarium. There are three primary functions that the best filter for an aquarium will do. These primary functions are Biological filtration, Mechanical filtration, and Chemical filtration. Each plays a particular role that helps provide your fish with the safe home they deserve.

Biological Filtration:

The biological role of a filter is to eliminate waste from your tank. As fishes swim, they’re constantly producing waste which will quickly dirty your tank and make it uninhabitable. How the simplest aquarium filter conducts biological filtration converts your fishes’ waste into a less toxic substance to all fishes.

Mechanical Filtration: 

The mechanical aspect of a filter is to get rid of particles from the water. Mechanical filtration is straining the water to catch any of those free-floating particles that decrease the cleanliness of your tank. The filter features a sponge-like pad inside it which will catch the particles and eliminate them from the tank and gravel.

Chemical Filtration:

Chemically, the filter helps eliminate harmful impurities from the water, which will seriously harm and even kill your fishes. Activated filter carbon is in most filters, and it removes the chemicals within the water that are dangerous to fish. Since the tank isn’t free-flowing water, the filter will work to keep it from stagnation.
