Although purified water can be helpful for various purposes, it is not suitable for use in your betta fish tank unless you supplement it with nutrients, minerals, and pH-balancing chemicals.
To purify the water filter will be the best option, cleans the water of debris, removes toxic ammonia and nitrate formation, and oxygenates the water so your fish can breathe. If you do not do this, your betta will not thrive and may even die.
This article will show you the best small aquarium filter for your betta fish, which will help keep the water in your betta fish tank balanced.
So, let’s start with the question: What should be considered before buying an aquarium filter?
The filtration flow rate is an important consideration. Find a filtration system with an adjustable flow because delicate plants or corals require a flow rate. If you have these two types, you should think about the filter flow rate.
The amount of water produced in a reasonable amount of time is the second factor to consider. Another important consideration is the number of filtration stages.
A good filter should have at least three filtration stages, including mechanical, biological, and chemical filtration. Now, my friend, we are just getting started.
