Filter Floss is more efficient than other mechanical filtration. The sponge is also considered to be the most used filter for aquariums. Although the sponge is cheaper than the filter floss, it is less effective.

After using filter floss, you do not need to wash your tank filter media because it collects the waste and dirt present in your filter media.

As a result, all the waste and dirt of your fish tank is ready to be thrown out in the garbage without much effort. Therefore, you do not have to clean your filter media from time to time, as it will be cleaned by filter floss itself.

Filter Floss is a quicker and effective way to get rid of debris. However, you can get in difficulty using filter floss if you are a beginner. Therefore, in this topic, we are going to discuss the things which you need to consider while using filter floss.

Potential To Raise Nitrate Level

A very controversial fact about filter floss is that it can raise the nitrate level of your aquarium. If you are an experienced aquarist or even just an enthusiast, you know that rise in nitrate level affects your fish haphazardly.

However, this is not the case in every filter floss. The waste and debris collected in the filter floss affect the nitrate level of your aquarium water. As a result, your fish may be hunted down by nitrate poisoning. Besides, it can cause the fish to be stressed as well as vulnerable to diseases.

Change Your Filter Floss

To stop your filter floss from raising the level of nitrate in your fish tank, all you have to do is change it out every 5 to 7 days. The risks rise as the number of days rises. So, remove the filter floss to clean the waste. Moreover, you can also decline the risks of decaying debris inside your fish tank.

Set Up Right Next To The Intake

Most beginners make a common mistake by not setting up the filter floss right next to the intake. What does setting up your filter floss right next to the intake of your tank do?

It makes the water go through your floss first, making your water clean before mixing in your tank water. This act is a relief for many people, as changing the water frequently becomes low.

Steps To Set Up Your Filter Floss

To set up the filter floss, for beginners, is quite a complicated job because there is not much information on the internet. Therefore, we have come with the steps to set up filter floss, and they are as follows:

Measure The Area

Firstly, you need to measure the area of your filter in which you are going to set up your floss. The length and breadth are the only topics of concern here. So, you do not need to worry about depth.

Cut The Floss

After measuring the area, you have an idea about the dimensions of the area where you will be playing. Now, cut your floss by using sharp scissors or box cutters to avoid chewing of floss. You need to make sure while cutting that the floss does not float in the water of your tank.

Furthermore, you have to be careful while cutting your filter floss. You can be cost-efficient if you cut your filter floss properly. You could always combine the pieces left, but it would not work as correctly as a single piece.

So, make sure that you measure your filter floss correctly and then cut it to save some extra dollars.

Place It In Your Aquarium

After you have cut down your floss into an appropriate size, you can place it into the spot where you had previously measured. You can also fold your floss if needed. Majorly if the floss is thin, you should undeniably fold it to collect the dirt and debris!

Therefore, by following these steps, you can set up your filter floss in your fish tank.
