What is a Betta Fish Tank Filter and What Is Its Role

To put it simply, an aquarium filter is a device that purifies water, fills it with oxygen, and removes harmful microorganisms or prevents their growth. Fish tank filters come in a great variety of forms, sizes, and modifications. That said, not all of them are equally great for betta fish. For example, betta fish, being small and lightweight, don’t feel comfortable when the flow is too powerful. So, you’d better opt for two smaller filters instead of one larger option.

The Best Products in the Category of Betta Fish Tank Filters: Our Choice

With so many various filter models on offer, choosing the best one is quite a challenge. We’ve conducted some research work to single out the most effective and reliable products in the category of betta fish tank filters. Now, we are ready to share this information with you.

Nano Filter by Aquarium Masters

Nano Filter by Aquarium Masters

Review

This hang-on power filter is designed specially for small and micro fish tanks of up to 4 gallons in size. It provides dual water filtration (mechanical + biological) and allows to adjust the water flow. The device is compact, ergonomic, and fits on all square and rectangular tanks.

What we think

This is a good entry-level option that does its job well, though it lacks some important features. For example, it misses the stage of chemical filtration with charcoal. Also, it doesn’t fit on round-shaped tanks, which reduces its versatility.

PROS

  • small and lightweight;
  • adjustable flow;
  • great for small tanks.

CONS

  • not for round-shaped tanks;
  • doesn’t offer chemical filtration.
Tetra Whisper PF10 Power Filter

Tetra Whisper PF10 Power Filter

Review

Tetra Whisper is a series of ultra-quiet aquarium filters. The PF10 option can process up to 10 gallons of water, providing a decent quality of filtration, consisting of three stages. Proprietary Bio-Bag disposable cartridges are included.

What we think

All in all, this is a great deal for the price. But you need to keep in mind (and many customers write about it) that the flow is not adjustable and it is way too strong for bettas. The solution is using two smaller filters instead of one large unit.

PROS

  • very affordable;
  • original disposable cartridges;
  • three stages of water filtration.

CONS

  • the flow is not adjustable.
Penn Plax Cascade Hang-on Aquarium Filter

Penn Plax Cascade Hang-on Aquarium Filter

Review

Penn Plax is one of the best fish tank filter options for small aquariums (of up to 7 gallons.) Thanks to its improved four-stage water filtration system, it provides a superb quality of water purification. Also, it offers an option of current flow adjusting, which is important for small and sensitive bettas.

What we think

This is a good inexpensive filter with a possibility to adjust the current flow. We’ve noticed that it becomes louder when the flow is reduced. Otherwise, we have nothing to complain about.

PROS

  • four-stage filtration;
  • adjustable flow;
  • budget-friendly.

CONS

  • a bit loud when the flow is reduced.
Aqueon Quietflow Internal Power Filter

Aqueon Quietflow Internal Power Filter

Review

This fully submersible compact filter can be placed both vertically and horizontally, which makes it one of the most versatile options around. On top of this, if offers to adjust not only the current flow rate but also its height and direction. The device comes with a limited lifetime warranty, which is also great.

What we think

This is an awesome option for those who for some reason (e.g. lack of space) can’t use external filters. It is compact, quiet, and effective. The only complaint is an average quality of suction cups.

PROS

  • fully submersible ergonomic design;
  • vertical and horizontal positioning;
  • good adjustability.

CONS

  • suction cups are mediocre.
Deep Blue Professional ADB88700 Biomaxx Nano Filter

Deep Blue Professional ADB88700 Biomaxx Nano Filter

Review

This nano filter works great for tiny aquariums and desktops. It comes with all the accessories, including sponges; plus, you can add your own filtering media if you wish. While being really small and cheap, it has some nice features, such as adjustable flow rate.

What we think

If you are looking for an entry-level for 2-4-gallon aquarium, you may love this nano-filter. Mind that it lacks the feature of chemical filtration. In other words, you get exactly what you pay for.

PROS

  • one of the smallest options around;
  • adjustable flow rate;
  • very affordable.

CONS

  • no chemical filtration.
