How to Choose the Best Filter For A Betta Fish Tank?

So those filters are some of the best filters that you can get. But let’s get a bit more specific. What exactly do you have to look for when you are buying a filter for your tank?

What are the specifications of the filter that will make it perfect for your needs? Let us take a look at some of the questions you need to ask yourself when choosing a filter.

Firstly, you need to know the size of the filter, and how powerful the filter is. This way, you will prevent the fish from suffering from a filtration that is too strong but also having too weak filtration which can cause the water to be poorly filtrated and full of debris. Make some research about the filter size.

Secondly, you need to know how much you are willing to spend on a filtration system. As you have seen, some are more expensive and some are a bit more on the budget side.

You do, however, get almost the same quality with some of the budget filters as you get with the pricey ones, but if you do want to make sure that you will have a top-quality filtration system, then spending a bit more on it would not go a miss.

There are some other factors like personal preferences, the convenience and ease of use of the filters and how will it fit in the overall look of your tank.

How to Setup a Saltwater Aquarium Filter?

Before you start the filtration system, you need to take care of some of the important things first. Prior to putting the filter into the water

it is preferred that you take the filter pads out of the filter and rinse and clean them thoroughly first, to prevent any dirty stuff from getting into the water. Then clean the whole back of the aquarium, where your filter will be.

It is then time to install the filtration system and mount it onto the back wall of the tank. You want to set up with a 3-stage filtration:

Mechanical filtration is the filtration of the bigger particles and chunks of debris from the water. This is the first part of any filtration system and it will keep the debris out of the water and make sure that the water is clear of any unwanted particles.

Biological filtration is the second part, and this part we cannot actually see, but it is also very important. It clears the water of ammonia, which is disintegrated by the beneficial bacteria and transformed into nitrites, and later into nitrates. These are much less toxic than ammonia and nitrites.

Chemical filtration is the last part of filtration. You may think that this part is not as important, but it is actually just as, if not even more, important than the other two parts.

With chemical filtration, the filter gets rid of some unwanted chemicals from the water, such as heavy metals, compounds, tannins, bad smells and more.

Make sure that you take care of all three steps of filtration to see the best possible filtration results.
