Things to Consider

With the number of sponge filters available on the market, it can be hard to identify the right one. Of course, you don’t want to pick any model that you come across. I have some important tips that will help you get a quality sponge filter to suit your needs.

Aquarium Size

Before you buy the right sponge filter, it is important to consider the size of your fish tank. You want to get the right size so that it can work well in your aquarium. If your fish tank is large, then you need to get a large sponge filter to get the right flow. If you also have a small fish tank, get a small sponge filter that fits well.

Types

You should also know that sponge filters come in different types. Unlike other types of filters, these filters are easy to maintain and they work well with different types of fish tanks. On top of that, you can use them to complement other filters like canister, HOB, and standalone filters. You can get the right model depending on the type of aquarium that you have. For instance, the types that you can get are suitable for nano tanks, large tanks, small tanks, and betta tanks among others.

Advanced Features

Sponge filters come with various features. Some have basic features while others have advanced features. For instance, you can get a double sponge water filter. Just like the name suggests, these are filters that have two filters and they offer a superb cleaning. You can also get some models with 3 sponge filters if you need more than just the normal filter. So, depending on your needs, you can pick the most suitable to suit your needs.

Your budget

How much money do you want to spend? This varies from one individual to another. It is important to set a budget and look for a sponge filter that matches your budget requirements. Sponge filters are affordable as compared to other types of filters. The price of sponge filters varies based on the features and the brand. Just make sure that you get the right model with the features that you want and meets your budget needs.

Installation

This is another thing that you should consider when buying a sponge filter. Setting up a sponge filter is easy even if you are new to keeping fish. With a sponge filter, you will only deal with the tubes, suction cups, and sponges which make installation easy.

Performance

You also want to have a quality sponge filter that works well. Can it produce beneficial bacteria?  This is important because cleaning your aquarium becomes a simple job. On top of that, it is wise to consider a model that doesn’t generate a strong current. Most of the sponge filters you will find on the market feature a gentle current and this makes them ideal for fish babies without worrying about the fish being sucked.

Quality and Design

Just like buying any other product on the market, you want something that can give you value for your money. In this case, you should buy a sponge filter that is quality. It should be dense such that it doesn’t float on the aquarium easily. When it comes to the design, ensure that it has various layers to offer many filtering stages.

Ease of Cleaning

This is another important thing that you should consider when buying a sponge filter. You need to get a model that is easy to clean. This is why many people opt for sponge filters. They are easy to clean as compared to other types of filters. Cleaning the filters is easy, you just need to rinse them and then squeeze them in the tank water. It is not advisable to use tap water because it will affect the beneficial bacteria that convert ammonia into nitrates.

Price

It is also great to consider the price. One great thing about sponge filters is that they come at an affordable price. You can get several in one package at an affordable price. Weight out your budget and then look for a sponge filter that is designed to meet your budget requirements. All the above filters I have covered come at affordable prices and they work amazingly well in keeping the aquarium water clean hence your fish will have a healthy environment to live in. 

How Often Should You Clean A Sponge Filter?

Sometimes you can find some large debris trapped in the filter. This affects the working of the filter and therefore needs frequent cleaning. You can clean your sponge filter after two weeks.

One of the indicators that will let you know that you need to clean your sponge filter is when you realize the water surrounding the sponge begins to get slow. Remove the filter and ensure that you have a container below. This will ensure that the filthy water and other residues do not get back to fish tank.

When lifting the sponge filter, put a little used tank water in a container and put the sponge in the container. Squeeze it until nothing comes from the sponge. Return the sponge in the tank and then get rid of the dirty water in the container. You also need to add some conditioned water.

How Does A Sponge Filter Work?

The working mechanism of a sponge filter is not complicated. The filter is easy to use and it works in a simple manner. Once you buy your ideal model, power it using an aquarium air pump and ensure that the air tubing is located at the center. The air tube works well to remove the air from the pump.

This brings about the pressure that pulls water and passes through the filter. This pressure traps floating debris in the water and this keeps the water looking clear. The sponge traps the solid waste that you can choose to remove manually. Also, it can be converted to food for the bacteria. The wastes produce toxins that are bacteria-friendly and they are converted into safe nitrates.  When you are changing the water weekly, you can get rid of the nitrates.
