Best Sponge Filters For Betta Tank
#1 Hikari Bacto-Surge High Density Foam Filter
This is one of the best sponge filters we can find today. If you are looking for the quietest filter for a betta fish’s tank and no clutter for your living space, this is the best choice.
This filter from Hikari is not only quiet but it works really well with betta fish tank powder. It can quickly clean an opaque betta tank or remove impurities inside the tank.
This product works well with betta tanks ranging in size from 5 gallons to 15 gallons. And you really don’t need to do much with this filter. No complicated settings or no confusing when used.
As we mentioned above, the biggest advantage of this product is that it doesn’t make much noise and does not scare the betta in the tank. Besides, it has another advantage that it does not create any strong water oscillation.
That means this filter does not create currents that can frighten the betta. Instead it produces only small bubbles of air, which do not produce any other water fluctuations. This factor is extremely suitable for static water fish such as betta fish.
You also do not need to worry about the workability of this product. It is a quality sponge filter.
What you need to worry about is the uncluttered size of this product. It may be a bit too big for a betta tank and you cannot ignore its appearance either. However, you can hide it by using decorative tools or plants.
#2 XY-2831 Air Pump Sponge Filter for Aquarium
Another sponge filter that we think needs to be on this list. That is the filter from XINYOU.
This is an affordable sponge filter (if not quite cheap) and comes with a good performance. This product can filter biology and chemical filtration, bringing a better quality of water to your betta aquarium.
This filter has a powerful design, easy installation and ease of use. You can also hang this filter on the edge of the betta fish tank easily thanks to a suction cup. Therefore, you do not have to worry about the placement of the filter in the tank.
Like other sponge filters, it has the ability to retain good bacteria and does not create strong vibrations in the water. So it is not likely to affect the activity of betta fish.
It is also a simple design device so you can easily clean and maintain. This is a job that will take you a lot of time and it’s great when you can shorten it.
Although this filter is ideal for use with bettas from 10 gallons to 20 gallons, some customers are still not satisfied with its bulky size. It seems to occupy a large area in the betta tank.
Best External Filter For Betta Tank
#1 Fluval External Filter
Perhaps when it comes to canister filters, the name that many people think of first is the filter from Fluval. Fluval is a well known manufacturer for its high quality filters. Not only that, they also have an amazing life expectancy.
You can rely on the ability of this filter to work completely. It has the ability to filter biology and filter chemistry independently. It helps improve efficiency and does not interrupt the processes.
In terms of design, this is an external filter so you don’t need a headache to choose a filter placement within the modest space of the betta fish tank. You only need to take advantage of the space under the table or under the aquarium to place this device.
Despite its large size, it is not a powerful noisy device. You operate so smoothly and silently that it’s almost impossible to detect when it’s working or not. Therefore, you can place a betta aquarium in your bedroom.
This product also has an excellent lifespan because it is manufactured from durable materials. You can also easily clean the filter and have regular maintenance.
However the water generated by this device may be a bit strong for betta fish. And this is not a budget option for those who have a modest budget.
Best HOB Filters For Betta Tank
#1 Marina Power Filter
This filter from famous manufacturer Marina will certainly not disappoint you. It is an HOB filter with the ideal size, appearance and working ability for a betta aquarium.
This product has a simple and neat design. It is designed to fit the characteristics of an aquarium of less than 10 gallons. You also have many other options with tanks under 20 gallons and under 15 gallons. We will review the product in the intermediary.
This filter is a thin and transparent filter, does not occupy much space in the betta tank nor does it affect too much the overall appearance of the aquarium. That is why it is favored by many customers and becomes Amazon’s Choice.
Not only that, it also has outstanding biological filtration capabilities. That means the bacteria in water will be kept to the maximum and effectively eliminate harmful bacteria and other impurities.
You can also adjust the flow rate of this filter flexibly. However, the flow rate after adjustment can still be a bit strong compared to static water fish such as betta. So you may need to use additional partitions to reduce that strength.
#2 Aqua Clear – Fish Tank Filter
Certainly this list cannot be without the HOB filter from Aqua Clear. Perhaps this is the best selling product on this list and you should also trust the majority.
This HOB filter has an extremely respectable performance. It can filter a large volume of water in just a short time. And it will also continuously work so that the water in the betta fish tank is filtered repeatedly.
Therefore, the quality of water in the aquarium will be significantly improved. The device can also effectively filter biological and chemical filters, keeping the betta in its healthiest state.
You can also change the speed of the flow easily. Because the tank size is from 5 gallons to 20 gallons, the flow rate is not too strong.
However it is not a completely silent filter when operating. But luckily, these noises are not too loud to drive you crazy.
Best Undergravel Filters For Betta Fish Tank
If you love the design of an undergravel filter, don’t miss this product from manufacturer Lee’s. This product is highly flexible and has an excellent working quality and durability.
This filter has up to 4 carbon cartridges so it increases the efficiency of filtration for the betta aquarium. This product also plays a good role in biological filtration and chemical filtration. You can be assured of its filtration efficiency.
In addition, this premium undergravel filter also comes with 8 ports. That means this product has an exceptional flexibility. Through these ports, you can connect with many filters or other additional devices.
You can also easily adjust the flow rate of this filter to match the betta fish. The flow rate is adjustable from low, medium to high. However, you should choose low speed micro betta fish as silent fish.
This filter also does not cause any strong water fluctuations. It only emits small bubbles and does not affect the betta fish.
It also has a nice design so you don’t have to cover it up with other decorations. You just need to put on the surface of it a little gravel to make the appearance of the aquarium more beautiful.
But this filter seems too strong for small sized tanks.
7 Tips To Choose The Best Filter For Betta Tanks
Before investing any filter for betta tanks, you should never be in a hurry but take some time to research a bit. Rushes will only lead to wrong investments.
That’s why we have prepared some helpful tips to help you choose the best filter for betta tank.
#1 Choose adjustable flow rate
Because betta fish are silent water fish, strong fluctuations of water will affect them. Therefore, you should choose a filter that can adjust the speed of the flow.
Or you can choose filters with low flow rates, so that you do not need to worry to adjust it.
#2 Easy to maintain
You should really choose filters that can easily be removed and simply reinstalled. This element will help you to clean the filter easily to ensure they are always in the best state.
Easy maintenance will also increase the life of the product and will not affect the health of betta fish.
#3 Filter media
You really need to find out about product filter media. Find out if this filter has all three chemical, mechanical or biological filtering capabilities. Or that filter is only capable of mechanical filtration.
These media filters will directly affect the water quality in betta pools. A product with multiple media filters is more efficient than a product with only one media filter.
#4 Endurance considerations
Durability of the product is also a way for you to judge whether the product is good or not. Find out if the product is made of any material, whether it is durable or not. Or find out if this filter is clogged or not.
You can get this information from previous customers’ reviews. Or you can also search through forums and reviews.
#5 Consider the size of the betta tank
The size of the betta aquarium will directly affect the type of filter as well as the size of the filter.
If your betta tank is large, the choice of filters will not be limited. However, for small sized tanks, you really need to consider carefully.
You should choose small sized filters so as not to affect the fish or other objects or equipment in the tank. You can also choose a HOB filer or external filter to maximize the free space for your betta aquarium.
#6 Consider the aesthetics of the filter
A betta aquarium not only helps you relax with these beautiful little fish, but it is also an outstanding decoration for your living space.
Therefore, you need to pay attention to the aesthetics of the filter to see if it fits the overall overview of the betta aquarium.
If you have no other choice but to choose a non-aesthetic filter, consider hiding it.
You can do this by using any of the available aquarium equipment, and don’t forget to arrange it in the most natural way.
#7 Budget is also important
If you have a limited budget, never buy low quality products and super cheap price. These products may work well for the first few days, but after that you will not be able to continue using it a second time.
Currently many famous manufacturers have many products that are affordable and able to work well. Therefore, you should spend a little extra budget, instead you will receive a product with high durability and quality assurance.
A betta fish tank cannot function without a filter. The filter will help keep the betta’s habitat clean and remove all other impurities.
However, you should never rush to invest in a filter without learning much about them. You should take the time to research some basic factors so you can choose the product that best suits your needs.
