Factors to Consider in Selecting a Goldfish Tank Filter

When choosing a filter for your goldfish tank, the following factors should be considered:

The Size

The size of your goldfish tank is measured by the number of gallons of water it can handle. If you do not consider this when getting a filter tank, your tank would not be a safe environment for your goldfish, and their health could be at risk.

The Type

Aquarium filters for goldfish are available in different types like canister filters, sponge filters, and power filters.

Canister Filter

Canister filter uses electricity to operate and a water bar in dispersing the outflow of contaminant-free water on the bar. This is best for saltwater and planted tanks. This type of tank filter requires less maintenance and has a reusable filter media. Space is also not an issue with this type of filter, as it requires less space behind the tank. It is housed below, and only the tubes are required to get behind the tank.

This type of filter offers high filtration capacity, and one unit can handle a huge aquarium. Water flow can be controlled to achieve various flow patterns inside the tank. However, the canister filter is not easy to clean.

Hang-on-Back or Power Filter

Hang-on-back filter also uses electricity to pull the water into filtration cartridges. This type of filter is hanged on the side of the fish tank. Thus, it is called a hang-on-back. As compared to a canister filter, HOB is easy to maintain but a little bit pricier because it requires you to change the filter media regularly, which makes it is an on-going expense. Installing it is easy as long as you have enough space behind the tank.

This filter uses a waterfall type return system that cannot be modified as compared to a canister filter. These filters are not enough for large tanks if used singly.

Sponge Filter

A sponge filter is usually used in breeding tanks and is being powered by an air pump. The aquarium water is drawn through a sponge found inside or mounted at the fish tank. This filter has a replaceable sponge.

The sponge can be installed on the bottom of the tank, where you can place it on, in, or underneath the gravel. Some models will mount inside the tank and placed near the bottom to provide maximum water circulation.

Flow Rate

Remember, the flow rate will depend on the size of the aquarium. Thus, if you have an aquarium with 30 gallons of water, the filter can turn over for approximately five times the amount of water, or 150 gallons per hour. An excellent flow rate of water can assure you that your aquarium will be cleaned at a speed that is not too slow or not too swift.

Filtration Technology System

There are three kinds of filtration system:

Biological filtration

This type of filtration occurs when specific bacteria are diffused with the help of beneficial bacteria. The filter will keep the beneficial bacteria stay and prevent the formation of the harmful types of bacteria.

Chemical Filtration

This filtration involves the passing of hazardous chemicals into the filter. Also, this filter is designed to lure those types of molecules and get rid of them from the water.

Mechanical Filtration

The process includes the forcing of water into a filter designed to capture any debris or filth during the transfer.

Generally, these filtration processes are needed to have a healthy and clean fish tank. Therefore, investing in a high-quality tank filter that is equipped with all the three filtration process is the most practical one.

Why is Filtration Essential for Goldfish?

Goldfish come in different varieties and colors. They are usually sold as small juveniles but can grow up to 12 inches in length and are placed in a bigger aquarium. They are small, but they need to be placed in a medium or large-sized aquarium.

Fish bowls need water changes every day and will work best only when the fishes are very small. They will not survive in this condition as they become bigger. Keeping them in small tanks or bowls is a disaster, and your fish will not survive long.

If you want to keep multiple goldfish of different varieties, you should use a 50 gallons aquarium. This kind of tank requires a substantial filter system to make sure your goldfish have a clean and safe environment to thrive.

Choose a tank filter that can provide mechanical and biological filtration. If possible, get a filter tank where you can adjust the tank’s chemistry to provide the safest and healthiest environment for your goldfish. Filtration is one of the secrets in maintaining a healthy environment not just for goldfish but for all types of aquatic pets.
