How to Choose Best Aquarium Filter for Large Tanks: Buyer’s Guide

If you are looking to purchase an aquarium filter for a large tank, there are a few things you need to take into consideration before making your purchase. This buyer’s guide will help you to choose the best aquarium filter for large tanks, based on your specific needs.

What Is A Aquarium Filter?

Aquarium filters are devices that help to remove waste products and toxins from the water in your fish tank. By doing so, they create a cleaner and healthier environment for your fish to live in. It is important to choose the right filter for your particular aquarium setup in order to ensure the health and wellbeing of your fish.

Different Types of Filtration

The first thing you need to do is decide what type of filter you need. There are three main types of filters available on the market: mechanical, chemical, and biological. Each type of filter has its own set of pros and cons, so you will need to decide which one is right for your tank.

Mechanical filters are the most common type of filter used in aquariums. They work by trapping debris and particles in a media, such as a sponge or filter floss. This type of filter is very effective at removing physical waste from your tank, but it does not remove dissolved waste or toxins.

Chemical filters work by using chemical media to remove dissolved waste and toxins from your water. Chemical filters are less effective at removing physical waste, but they are much better at removing dissolved waste and toxins.

Biological filters are the most effective type of filter for removing both physical and dissolved waste from your water. Biological filters use bacteria to break down waste and toxins in your water. This type of filter is the most expensive, but it is also the most effective.

Once you have decided which type of filter you need, the next step is to choose the size of the filter. The size of the filter you need will depend on the size of your tank. It is important to choose a filter that is big enough to handle the amount of water in your tank, but not so big that it takes up too much space.

The last thing you need to consider when choosing an aquarium filter is the price. Filters range in price from a few dollars to several hundred dollars. The price you pay for your filter will depend on the quality of the filter and the features it offers.

Types of Aquarium Filters

Aquarium filters are an essential part of any fish tank, providing vital filtration and circulation while helping to maintain water quality. The type of filter you choose will ultimately depend on your specific needs and preferences.

Type 1: Canister Filters

Canister filters are one of the most popular types of aquarium filters. Canister filters are external filters that hang on the back of the aquarium. They are very powerful and can filter large amounts of water very quickly. They are more expensive than under gravel filters, but they are also much more efficient.

Canister filters work by drawing water through a series of tubes and filters. Canister filters also have a lot of room for media, so you can customize your filtration to your specific needs.

The biggest drawback of canister filters is that they can be difficult to set up and maintain. Canister filters also require regular cleaning, as the media can become clogged over time.

Type 2: Hang-on-Back Filters

aquarium with hang on back filter

Hang-on-back filters are a popular type of aquarium filter for beginner aquarium hobbyists. Hang-on-back filters are easy to set up and maintain, and they are usually less expensive than canister filters.

Hang-on-back filters are not as powerful as canister filters, and they do not have as much room for media. Hang-on-back filters are best for small to medium-sized aquariums.

Type 3: Undergravel Filters

Undergravel filters are a type of aquarium filter that is placed under the gravel in the aquarium. Undergravel filters are relatively easy to set up and maintain.

Undergravel filters work by drawing water down through a layer of gravel, which traps impurities. These filters require regular maintenance, as the gravel must be cleaned periodically to prevent it from becoming clogged.

However, they can be difficult to clean and maintain, and they are not effective at removing dissolved wastes from the water. They are best for small to medium-sized aquariums.

Type 4: Power Filters

Power filters are a type of aquarium filter that is hung on the back of the aquarium. Power filters are a good option for smaller aquariums or for those who want a simple, easy-to-use filter.

They provide good filtration and circulation. However, they are not as effective at removing dissolved wastes from the water. These filters require regular maintenance, as the filters must be replaced periodically.

Power filters are not as powerful as canister or hang-on-back filters. They are best for small to medium-sized aquariums.

Type 5: Sponge Filters

Sponge filters are a good choice for aquariums with small fish or sensitive fish. Sponge filters provide good filtration and circulation while being gentle on fish. However, they are not as effective at removing dissolved wastes from the water as other types of filters.

How to Install and Maintain an Aquarium Filter?

No matter which type of aquarium filter you choose, be sure to read the instructions carefully and follow all manufacturer’s recommendations to ensure proper installation and use.

Installing an Aquarium Filter

In order to install the filter, follow a few simple steps:

  1. Place the filter in the aquarium. Most filters will need to be placed under the gravel or behind the aquarium glass.
  2. Connect the filter to the power source. Follow the manufacturer’s instructions for doing this.
  3. Fill the filter with water. This can be done by pouring water into the filter or by using a siphon.
  4. Prime the filter. This means turning on the power to the filter and allowing it to run for a few minutes without fish in the tank. This will allow the filter to start working and remove any air from the system.
  5. Add fish to the tank. Once the filter is running smoothly, you can add fish to the aquarium.

Maintaining an Aquarium Filter

To make your ribs feel great follow a few simple steps:

  1. Clean the filter regularly. Most filters will need to be cleaned every few weeks. This can be done by disassembling the filter and using a brush to remove any debris from the parts.
  2. Replace the filter media. Most filters have replaceable media that will need to be replaced every few months.
  3. Check the intake and output valves. These should be checked regularly to make sure they are working properly.
  4. Monitor the water quality. Aquarium filters will help to keep the water clean, but it is still important to monitor the water quality. This can be done by testing the water regularly and making sure the levels of ammonia and nitrites are low.
  5. Take care of the fish. In addition to keeping the water clean, it is also important to take care of the fish. This includes feeding them properly and keeping them healthy.

  1. I have two aquariums, a 150 gallon and a 30 gallon. I bought a Penn-Plax Cascade 1500 Aquarium Canister Filter for a 150 gallon aquarium about six months ago. So far so good. Thinking of getting another 200 gallon aquarium, liked your article. I’m leaning towards the Fluval FX6 High-Performance Aquarium Filter for now. Expensive, of course, but I think everyone praises it very much. I will think about which one is better to buy.

    Reply
    • Good afternoon, Mark!
      Yes, I understand you, I too have a Penn-Plax Cascade 1500 Aquarium Canister Filter. Generally Fluval is a good company, my friend has a Fluval 07 Series Performance Canister Filter for Aquariums. The filter is easy to install and includes all the filtering materials you need to get started. However, I would recommend switching from the cheaper ceramic rings supplied to the Fluvals Biomax ceramic rings or better yet, the Seachem matrix, as it can also support nitrate-eating bacteria, unlike the ceramic media, which cannot.
      The only drawback to this filter is that the inlet and outlet fittings that attach to the top of your tank are pretty cheap and flimsy, and only suction cups hold them in place, which makes it hard to install them straight and not get it. Pulls aside with the hose tension and they also have one suction cup on the front and one on the back to grip the glass on both sides, but if you have a background, the back cup won’t stick to it!
      The solution to this problem is that the All Pond Solutions filter hoses and fittings I mentioned earlier fit the 107 and 207 perfectly and are sold on their website. Be sure to purchase their hose, as the Fluval hose does not fit APS fittings! The All Pond Solutions inlet and outlet is much stronger and attaches to the glass for a better fit, and includes a sprinkler that is sold separately with Fluval. Read up on some more information to make a definite decision about the model already.
