7 Best Small Hob (Hang on Back) Aquarium Filter

Small tanks and larger tanks, always require a good filter because fish excrete waste constantly as they swim around in the water. Currently, the HOB-PF Hang-on Back Power Filter is a visually appealing and versatile filtration unit ideal for aquariums.

This power filter has a convenient drop-in media basket with a removable divider plate that allows you to easily change and customize your filter media. 

They always have adjustable flow rates, allowing you to reduce the flow when feeding your fish, and they also produce less heat and friction in the water. In this article, we’ll help you find a good quality HOB filter for your aquarium.

So, let’s start with the question: What things need to remember before buying a HOB power filter?

The first important factor to consider is the number of filtration stages. A good filter should have at least three stages of filtration, including mechanical, biological, and chemical.

The second filtration flow rate is an important factor to consider. It is recommended that the flow rate be at least four times the capacity of your fish tank. For example,  40-60 gallons per hour is ideal for a 10-gallon aquarium.

The last factor to consider is the amount of water that can be produced in a reasonable amount of time.

Frequently Asked Questions

How many hours should the aquarium filter run?

The flow of water through the filter is what keeps your fish safe in the water. An aquarium filter should filter all of the water in the tank at least three times per hour. It is too small if it does not.

How many fish can I have in a 10-gallon tank?

Aim for one small fish per gallon of water at first, adding them in small groups every couple of weeks. You should be able to keep two neon-tetra-size fish per gallon once the aquarium has matured and your skills have been honed.

Should I turn off the filter when feeding fish?

If your filter pushes water downwards, it may be good to turn it off during feeding to avoid food sucked.

The filter is a must for any aquarium but it should be chosen according to the comparison, and you must ensure that the filter you choose has appropriate filtration media and a reasonable flow rate for your fish.
