Your Fish Tank Filter Buying Guide

You do need to look at certain things before you go on making your purchase. Straight away, there’s no best fish tank filter, so you need to find out what makes a good fish tank filter. Here are some of the main things that you should know:

  • Filtration Type:

For water filtration, there are three different kinds: chemical, mechanical and biological.

Chemical filtration doesn’t come with every aquarium filter, but it surely is a need for your system. The chemical filtration is what filters out toxic and unwanted chemicals from the water to enhance its quality. Some rare fish breeds may have some specific preferences for the water that they will be in, so you need to modify it accordingly. If your ordinary tap water contains high levels of chlorine or other harmful chemicals, you will need a chemical filtration to maintain a healthy water balance.

Mechanical filtration removes any unnecessary particles from the water. Hence, it keeps the water crystal clear and free of any unknown particles floating inside the water. Mechanical filtration also removes different sized particles by flowing through various types of media.

Biological filtration focuses on the micro-life inside the aquarium. Fish waste creates a lot of toxins byproducts in the water. By maintaining beneficial water bacteria, the biological filtration enhances the breaking down of ammonia into nitrates that could be utilized by plants or removed through regular cleaning and water changes.

  • Filter Type:

There are a number of different styles of filters that you could choose from. However, you need to ensure that the filter type matches your needs. Some forms are better than the others, but always choose the one that fits with your aquarium.

Internal filters usually sit inside an aquarium, generally at the top of the tank. It can be mounted with suction cups and then nestled on top of the substrate that’s attached to the corner of the tank. These filters mainly rely on air to push up from the bottom of the filter and then move water through it. They come with sponges and activated carbon with them. These are low-flow filters that are designed specifically for smaller tanks.

Under gravel, filters pose underneath the gravel substrate in the tank and work by flowing water in through slots on the top. Most under gravel filters concentrate on mechanical filtration rather than chemical or biological filtration. They work great on smaller tanks but requires more maintenance than the other types of filters.

Hang on back filters, also known as power filters, hang on the outside of an aquarium with a small tube that reaches inside to cycle water through. The more substantial hanging part of the filter can be broken down into several cartridges containing media for chemical, mechanical and biological filtration. An external filter as such is easier to maintain and come with an array of sizes for different tanks. They do not make excellent filters for small aquariums, the water of which can easily get disturbed by strong water flow.

Canister filters are customarily installed outside of a tank that forms a pressurized flow of water. They are mostly preferred by fish enthusiasts because it draws water in with a siphon and runs it through separate filtered sections, which by the way, performs all three types of filtration. As a pressurized system, it doesn’t need gravity or air to move water; chemical and mechanical filtration are good enough in such filters, while biological filtration is restricted.

Sump filters come with a heater and water pump. Previously, sump filters were mostly used in saltwater tanks, but nowadays, it’s used in both freshwater and saltwater tanks. It has a very simple design that’s relatively efficient, especially for larger tanks. Let us tell you that sump filters make excellent filters because of its ability to store more media than an ordinary filter. You can bring extra water volume to the system that is definitely beneficial for your tank.

  • Capacity (Flow rate/strength):

Fish tank filters are designed in such a way that it works within a certain power range. The strength of it sometimes mentioned in units of power like volts is the capacity the filter can take up to. We would recommend you to choose a filter that can support your aquarium or a larger one. Never go for a filter that is intended for a smaller sized tank.

 

How To Choose The Right Aquarium Filter:

Size Does Matter

It’s crucial that you need to match your filter to your aquarium size. You might see that the water inside the aquarium is crystal clear, but in reality, it could be affecting the life of your fish, plants and other marine beings. Make sure that you don’t overwork your filter.

If your tank is 55 gallons, you need a filter that can handle 55 gallons or more. It’s a better idea to buy something that’s able to do more than less. Without an appropriately sized filter, you will see a loss in your aquarium life.

Aquarium Filter Brands

Branded products are always “the best.” Although they are a little expensive, they are more reliable than others. Consider Penn Plax, AquaClear, Marineland, Eheim, and Fluval, they are not just reliable but also guarantee a better product overall. These brands come with uninterrupted service for years after years, needing little to very less maintenance.

Flow Rate

Again, the flow rate is significant because it deals with the speed at which your aquarium will pass water through the filter. It’s best to have a filter that’s able to turn over your aquarium water within a mere 4 hours. For instance, a 40-gallon aquarium will need a filter with a minimum flow rate of 125 gallons per hour (GPH). Typically, it is always the maximum GPH to even out the situation.

 

Frequently Asked Questions (FAQs)

Q1: Does my small aquarium need a filter?

Answer: Of course it does. No matter how small or large your aquarium might be, the fish and plants inside it are always producing waste. The purpose of a filter is to maintain a lively and healthy environment, minimizing your trouble of changing the water every single day.

Q2: Do I need to clean my fish tank filter?

Answer: Today, most of the filters are maintenance-free, but we’d still recommend you clean it out at least every 2 – 4 weeks. If it is operating at an upper range of its abilities, clean it out more often.

Q3: Do all the fishes produce the same amount of waste?

Answer: Not really. Some fishes are a little messier than others. For example, goldfishes and cichlids produce more waste than neon tetras. Messier fishes need a stronger filtration to maintain the same water levels. If your existing filter is not able to work very well, adding more fishes or messier fishes could lead to an unhealthy environment out there.

Q4: Can I just purchase and use a filter right away?

Answer: Certainly! However, biological filtration is an integral part of making sure that water quality remains consistent. Once you buy a new filter, it may not have the beneficial bacteria needed for your aquarium, but you can kickstart this process by using the media from an established tank.

That’s why we would recommend you to operate the fish tank manage for one week before you put in any fish to it in order to let the filter built up some beneficial bacteria. This is what’s called “cycling.”

Q5: Which is the best fish tank filter?

Answer: There’s no lousy fish tank filter; all of them are good. Our personal favorite is Eheim, because of its construct. However, the rest depends on your needs.

 

Tips For Maintaining a Healthy Fish Tank

  • Cycle the tank before you go on to add more fish. Take every step possible to bring in the water condition that is healthy for the fishes.
  • Test and monitor the water parameters. There is some very inexpensive water testing kit that will help you test and monitor the pH balance, ammonia, nitrite, and nitrates in the water.
  • Perform frequent water changes. Although it’s a little troublesome to change the water of the fish tank every now and then, there’s no alternative than replacing the water to keep your fishes healthy.
  • Research about the fish you are about to purchase. Understand the fish’s temperament, space and how big or small it might be for your aquarium. Never overcrowd your aquarium; that’s the worst you could ever do.
  • Never overfeed your fish. Feeding them once a day is enough. You need to starve them neither overfeed them. Fish food, it persists in the water for too long may turn out to become poisonous for your fishes.
  • Adjust the light in and around your aquarium. Avoid the aquarium from getting direct sunlight throughout the day time. A smart way to expose them to the sun is when you are at home and keeping it dark while you are away.

 

Final Words

Undoubtedly, fishes make fantastic pets. Although they stay underwater at all times, they are still not the cleanest of all. Whenever fishes do their business, it’s all left floating on the water in the tank that you can see. You surely need a filter if you want to maintain a clean and healthy aquarium.
