Guide to choose best fish tank filters – aquarium filters reviews

Maintaining a fish tank is an absolute excitement. Anyone can spend hours doing nothing but looking at lively fish moving across the tank. However, facts like polluted water, food waste and other debris can completely ruin the looks of your fish tank and make it very unhealthy for fish. The most effective and practical way to keep your fish tank or aquarium clean is by installing fish tank filters. In other words, you cannot expect your fish tank to be a beautiful and healthy place. When you shop around for aquarium filters, you might come across a variety of filters in the market and selecting one of them can be quite a challenge. The following guide to choose best fish tank filters and aquarium filters reviews will be of assistance for you when selecting the best product.

Usage of fish tank filters

The obvious reason of using fish tank filters is nothing but cleaning the water. Aquarium filters can get rid of elements like food residue, organic matter that pollute water, particles that flow on the surface of the water, hazardous chemicals and fish waste and make the tank a pleasant and healthy place for fish.

Fish are living organisms as we all know; so they excrete inside the tank while swimming around. You must remember that water in the tank doesn’t flow. So, if you don’t get rid of this fish waste, it will gather over the time inside the unchanged water and eventually become toxic for fish themselves. The ammonia levels of this water will rise making it really uncomfortable for fish. Ammonia contaminated water will eventually become poisoning for fish. Apart from that, floating food particles and other organic materials will make the tanks a more unpleasant place.

However, with the use of aquarium filters, you will be able to bring back the fresh, clean and healthy appearance to the tank. Once you find the correct type of fish tank filters, you can expect fish to be more active, strong, dynamic and beautiful.

Different types of fish tank filters and introduction

Aquarium filters available in the market in various forms. The functionality of these filters differs from one model to another. In general, the filtration process of an aquarium can be done as a biological, mechanical or a chemical process. This particular categorization is done considering the functionality. Generally, biological filtration is deployed in order to minimize the overall maintenance process of the aquarium. However, filtration processes like chemical and mechanical filtration are too required depending on the situation. Basically, mechanical filtration process is carried out to maintain the clarity of the water. Meanwhile, chemical filtration looks after the quality of the water by neutralizing (or eliminating) toxic substances from the tank water. So, you must keep in mind that just because the water is perfectly clear to the naked eye, it is impossible to be 100% sure that it is toxic free if you haven’t filtered it correctly. On the other hand, even the shadowy water can be good for fish to live in despite the unpleasant appearance.

  • Biological filtering

    Waste of your fish is toxic particularly when they are gathered over time. Ammonia percentage will rise remarkably and eventually water will no longer be suitable for fish to live. This is when biological filtration is required; the main role of biological water tank filters is to convert these toxic ammonia substances (which occur in the form of fish waste, dead fish and plant waste etc) into friendly nitrite. You must, however, still know that even nitrite is somewhat harmful for fish (liver and eye-related issues can occur on fish when exposed to nitrite for long periods). Even this nitrite should be removed from the tank with regular water changes. Other than that, nitrite might promote algae growth.

    In general, biological aquarium filters operate based on a cycling process. The efficiency of biological fish tank filters depends on the success of cycling.

  • Mechanical aquarium filters

    Mechanical filtration process is called particulate filtration too. Mechanical fish tank filters functions in a way that sends water through a strainer (which is the filter). When water is sent through this strainer, it will retain the particles and send out particle-free water to the tank. The strainer can be made out of materials such as filter pads, sponge, floss, gravel etc. The efficiency of a mechanical filter, however, will be influenced by several factors.

    • The quality of the media
      If the strainer media inside the aquarium filter is fine, it can retain even the finest particles. But, you should also know that these finer filters need to be cleaned quite frequently due to obvious reason; they retain more particles than the other fish tank filters that have coarse strainers. Modern mechanical fish tank filters come with several filtration layers in order to facilitate better cleaning process.
    • The amount of water filtered
      If your aquarium filter takes longer time to filter water (less amount of water is sent through the strainer per hour), more particles and debris will collect. Gradually, the water will become unclear and make the water unhealthy for fish.
    • The frequency of cleaning
      If you clean the strainer of the aquarium filter quite frequently, you can expect better efficiency. Also, you must check for the damages; a damaged strainer will significantly reduce the efficiency of the cleaning process. Therefore, it is always important to maintain the filer with good care.

    Apart from that, the quality of the water of the tank will affect the efficiency of the aquarium filter; dirtier water demands more work from the filter and the media will have to be replaced quite often. Generally, mechanical fish tank filters come with either a sump or a settling pool. When provided with a settling pool, it will make the larger particles to deposit at the bottom which will be removed.

  • Chemical filters

    Most of the chemical aquarium filters are based on carbon. In fact, carbon can extract variety of toxic substances effectively. Carbon filters work extremely hard to eliminate toxins from water. The system will work until the carbon material is worn off. So, it is obvious that you need to replace the strain (which is made out of activated carbon) frequently in order to maintain optimal performance.

The way they operate is different from one to another. Don’t think that any aquarium filter will fit your fish tank; there are several things to consider before buying a fish tank filter therefore. Here are the most important things you should consider when purchasing best fish tank filters.

  • Determine the GPH rate (Gallons per hour) of aquarium filters
    The GPH of a fish tank filter is often known as the flow rate too. This term explains the amount of water flows through the filter within an hour. If you use canister aquarium filters, you should clearly know the amount of water it filters per hour and see if they practically handles the capacity of the aquarium. However, the GPH rate greatly depends on what height the pump head is placed.

  • Be sure to purchase it from a reputed vendor
    There can be hundreds of vendors that sell fish tank filters both online and offline. Be sure to select a vendor that has a good reputation as a quality product supplier. You probably should read the testimonials page or the customer reviews section of the respective supplier’s website and get an insight to the quality of the fish tank filters they deal with.
