Keeping the water in your fish tank as clean as possible is important when ensuring your fish live problem-free lives. There is a very wide varied range of aquarium filters available and they are all designed to aid you, they are also ideal for use in fish tanks of varying sizes and capacity.
If you decide to use an internal filter, then they are ideal for providing filtration for small to medium size tanks and are a very cheap and practical way of keeping your aquarium clean, with very little maintenance of the actual unit required.
Are you looking to set up your own fish tank, but have so many unanswered questions concerning filters? Then you’ve come to the right place. After reading this article you’ll have most of the answers to your questions about fish tank filters.
What type of filter is best for a fish tank?
When thinking about getting a filter for your tank, there are several factors that have to be considered before you can decide on the best filter for your needs. Whether you choose a canister, sponge, power or HOB filter, it all depends on your particular situation.
One major factor to consider is the size of your tank because larger tanks need a more powerful system to process all the water. Powerful filters tend to be larger, which make external filters the best option.
You should also take the size of the room into consideration as small rooms might be best suited to internal filters because these sit inside the tank.
The purpose of your aquarium is another factor that will influence what kind of filter fits your tank. You should know that breeding tanks are well suited to sponge filters because the fry can’t get drawn in through the inlet.
The living species in your fish tank are also important factors as some plants and animals prefer a strong current because that is similar to what they would be used to in their natural habitat. A good option is a filter with a strong outflow of water to suit the needs of your inhabitants.
Fish waste should also be considered, as tanks containing greater biomass are harder for filters to deal with because more waste is produced. Due to this, a filter that processes more gallons per hour will be more successful at dealing with the extra waste.
Which is better internal or external aquarium filter?
As we said before, it all depends on the space of your room and how big your tank is. Internal filters are usually smaller, so if your room is small, this would be a good fit. But the problem with internal filters is that they aren’t usually powerful, this is where the external filters come in.
If you want a powerful filter and you have the space to house it, then an external filter just might be what you’re looking for.
What is the difference between a canister filter and a power filter?
When it comes to the debate on which filter to buy, the canister and power filters are usually the ones in competition. But we’ll give you a summary of their differences.
A canister filter is well known for its efficiency and versatility as it has the ability to use the 3 types of filtration methods (chemical, biological and mechanical). With the canister filter, you can choose which filtration method you want, you can even choose three different types of methods.
Canister filters (See best user rated canister filter) are usually big and are kept outside the tank, so water from the tank gets to the filter through tubes. They can hold a sizeable amount of water due to their capacity. The downside to this filter is that they can be harder to maintain, but despite this, they are really effective filters.
Power filters are very popular with people who keep small aquariums, it is smaller than the canister, and also much cheaper. The downside is that they are not as powerful as the canister filters.
What are the benefits of a canister filter?
One benefit is that canister filters are considered to be much more efficient than disposable or other types of fish tank filters. This is due to so many reasons, including the fact that you can choose the kind of media that is right for your tank. Due to the fact that the water is powered through the filter, the media will catch more of the waste. Possessing a variety of media allows them to tackle water problems such as ammonia and nitrites. These filters are good for reducing nitrate levels.
One other benefit of canister filters is that the clean water that has been filtered is able to be sprayed back into the tank in a way that reduces both splash and current and can also reduce evaporation as well.
For those of you that own a tank that needs to be placed in a way that is particularly close to a wall, a canister filter can be helpful because of the way it is situated. If you think about the fact that large tanks (or tanks that need to filter out a lot of waste) require a powerful filter, it makes sense to invest in a quality canister filter.
Can a canister filter sit next to the tank?
Placing the canister next to the tank would be better than placing it above or below it. This is because it will be easier on the pump as it won’t need to pump water against gravity. This will make your pump last longer as unnecessary stress isn’t placed on it.
Are canister filters quieter than hob?
As mentioned earlier, canister filters are more effective than HOB filters as they can contain more water and have more efficient filtration systems. Being able to do all these things comes with a lot of power which most times leads to a lot of noise. But canister filters have a way to take care of this noise which is the sound dampener, which reduces the noise to a bare minimum; a really great feature.
Although HOB filters are not that noisy, the sound dampener of the canister makes this filter not as noisy. So canister filters are quite than HOB filters.
How often should you change carbon in canister filter?
As a matter of fact, there’s no ‘definitive’ set of commandments on when to change your carbon filter medium, as efficacy can vary greatly depending on the following factors:
- The amount of fish you have in the aquarium which actively produce waste and impurities.
- If you put any foreign chemicals and treatments into the water system recently.
- What purpose does the carbon serve in the aquarium; for example is it being used to cleanse your aquarium water or remove waste products?
When you combine these three factors together you will know how often your carbon should be changed. But to be fair, the more livestock you have in the tank, the quicker the water will be contaminated with waste products. Because of this, the physical clarity of the water in your aquarium is the major indicator of how effective your carbon filter is; as the water starts to get cloudier, it’s probably time to start thinking about replacing your existing filter.
How do canister filters oxygenate the water?
Canister filters like all other filters can oxygenate the tank’s water by increasing the flow of water by the action of the pumps. The increase in water flow allows air to dissolve in water. This dissolved air in the water is what is used by the fish to breathe.
Can you over filter a tank?
It’s not possible to over filter the water in an aquarium and as the water can never be too clean. An increase in the filter media you run inside your tank the will better the tanks water cycle and in effect lead to having cleaner water. So in other words, you can never over filter your tank.
One downside might be that the filters will cause too much water movement for the size of the tank. Thus causing residents of your fish tank to be a little stressed out. So if you keep delicate angelfish, for example, you need to take care of water movement. Getting a small sponge fish tank filter can help solve that problem.
How do I get good bacteria in my aquarium?
You might have heard stories of people setting up their new aquarium and filling it with fish only to have them all die within the first few days, you know the result of not having enough good bacteria. One good thing is that good bacteria exists everywhere, including in the air and your tank’s interior surface.
One thing you can do is increase the ammonia source in the tank while constantly running the filter which creates the conditions for the bacteria to flourish. These good bacteria will set up shop in the aquarium filter where there is oxygenating water movement. When these organisms start flourishing, you’ll see a sudden drop in the ammonia levels and a steep rise in nitrites. And so bacteria that produce nitrates will start to take hold and will drop the nitrite and ammonia levels to zero.
Are sponge filters effective?
It’s good to note that sponge filters work using a very simple system. These filters possess a sponge shaped cylinder that is fully submerged in the water.
Filtration occurs when water is moved through the sponge by either an air stone or a water pump.
The problem with sponge filters is that they are mostly used as an additional filtration system. They cannot be used alone for large tanks with lots of fish. So if you’re looking to breed fish, a sponge filter might not be the best option.
