Aside from these, you also need to ponder on the size of the tank you are keeping, the number of fish dwelling in your aquarium, and many more.

Highly recommended filter media generally contain 2 of the basic forms of filtration. And chemical filtration is not often required.

Other Important Factors To Consider

What is an aquarium filter media? How does it work?

Filters are quite indispensable for aquarium health. These work by keeping the nitrogen cycle going and they execute very significant functions when it comes to keeping aquarium fish and plants livelier and in good condition.

A filter media is generally positioned in a tank’s filter that is meant to alter the quality of tank water that flows through it. And, since there are different types of filter media, there are certain kinds that you can get so you could possibly come up with the top-rated possible habitat for your aquarium dwellers.

In addition, there are 3 forms of filter media and these consist of chemical, biological and mechanical filtration.

What are the different types of filter media for aquarium?

There are three types of filter media and these comprise of:

Chemical Filter Media. This is not frequently utilized as compared to the other types of filter media. However, this could be efficient for different filtering purposes. It is available in a broad range of materials that could get rid of one or more impurities.

Essentially, this filtration approach eliminates dissolved particles from the tank through the aid of resins, activated carbons and other sorts of adsorbents. This method assists in sustaining water quality since undesired dissolved matter sticks to it.

The most renowned chemical media are resins and activated carbon. On the other hand, oxidation with ozone and protein foam skimming are just a few of the other types of chemical filtration.

Biological Filter Media. This is especially useful in that it enables good bacteria to thrive in the tank environment. It is significant to know that these bacteria are accountable for regulating the levels of ammonia present in the tank by disintegrating it in a natural approach.

Basically, it is crucial to let the bio media execute its job and changing it isn’t advised during the tank’s lifespan. To put it simply, all you need to do is to make it a habit of cleaning it in a regular basis.

It is fine to invest in commercially available bio filter media products like those made up of rocky substances or bio balls. These could be safely positioned in the aquarium’s filter’s sump and this could aid in keeping the water pristine clear and free of any hazardous ammonia levels.

Plus, there are some aquarists who prefer the use of absorptive live ocean rock that is meant to serve as the foundation for a new tank – note that these are usually used in marine tanks. In essence, rock serves as bio filter in keeping the nitrogen cycle in the most appropriate conditions.

Mechanical Filter Media. This kind of filter media contains inert components, which implies that they won’t do anything to hamper the tank water’s chemistry. In other words, it physically or mechanically filters solids from water that pass through it. Take in mind that this is very valuable for the effectiveness of your bio media.

This approach eliminates hideous particulates such as sludge, unconsumed food, fish feces or dirt. And, to ward off accumulation, the filter media must be periodically cleaned. Be reminded that replacement is merely necessary when the media can no longer discharge the filth that it holds.

This type of filter media is available in a number of distinct porosities that restrict the size of the particle they could siphon. The bigger the pores in the mechanical media, the bigger the particles must be so that the filter can siphon it.

It is interesting to note that coarse media is uncomplicated to clean and reuse as compared to finer media. While it is true that the finest media can clear the tank, this could congest quite rapidly and may not become reusable anymore.

Why do you need a fish tank filter media? (Benefits)

Needless to say, all aquariums need to be thoroughly cleaned and the tank water seriously needs to be strained regularly. However, the truth is there are specific aspects that you can’t eliminate in a conventional approach.

Due to this, it becomes a necessity to own a filter media if you are keeping an aquarium. This helps get rid of the hazardous particulates, chemicals and other substances that are present in the tank and could potentially bring about illnesses and may even cause the death of your fish tank occupants.

Various forms of filter media also help combat high levels of nitrate, ammonia and nitrite in the tank. They usually help create a foothold for good bacteria to thrive – as you know, these are beneficial in keeping a cleaner, safer and fresher hub for your aquarium pets and plants.

In reality, you can’t alleviate chemicals in tank water if you do it a manual mode, and it is impossible to build bacteria colonies inside the tank on your own. This is where the importance of owning filter media comes in. This is one sure way of removing bad chemicals from the tank.

These are very easy to utilize, they are not that expensive, and most of them are safe to use. Likewise, many options do not require frequent replacements as they are designed to be reused. And, since they are safe to use, this means that they are environment-friendly because they do not contain chemicals.

Frequently Asked Questions

Biological vs. Regular Filter Media: Which one is better?

Biological filter media contains inert components that are the ones responsible for sheltering healthy bacteria that disintegrate dissolved solids in a less harmful approach. It must not be replaced except when it has become congested and ineffective in executing its job.

On the other hand, regular filter media only concentrates on something that is positioned in a tank’s filter that helps modify the quality of water that flows through it. Thus, when comparing the two, bio-filter media is a better option.

How much aquarium filter media do I need?

How big the filter you will require will more likely rely on the current size of the aquarium you are keeping. You will prefer a filter that has the capability to cycle all the water in your tank by 3 by up to 4 times in an hour.

Meanwhile, a tank that contains 50 gallons of water commonly necessitates a filter that can cycle at least 14 times 50 GPH.

How often should filter media be changed?

The carbon media filter must be replaced once every three weeks to ensure its effectiveness. Unfortunately, this can’t be cleaned.

However, a mechanical media filter can be utilized till it breaks down on its own. Since the job of this filter media is to strain bigger pieces of residues, it could still function even if it’s not in ideal shape. Regular inspection is necessary, though.

If you are utilizing ceramic rings or bio balls, it matters to change roughly 1/3 at a time and this should solely be done if they start to disintegrate.

How much bio-media per gallon?

Most experts use a general guideline of at least 0.7 ounces per gallon for bio-media. But it can change from product to product, so it’s imperative to read the directions. For example, the AquaClear filter media for goldfish only requires 0.23 ounces per gallon to work.

The recommended amount of biological filter for the fish tank can also vary based on the fish itself. Some species can be quite sensitive, which calls for a higher amount of bio-media to maintain homeostasis to keep the fish comfortable.

What filter media removes nitrates?

There’s no need to use clean water to rinse the filter media. If anything, the old aquarium water will be most suited to remove waste from the filter media’s surface. But this step is where it becomes a little tricky depending on your specific filter media type:

• Chemical filter media: There’s no cleaning process for aquarium chemical filtration media. It’ll need replacing when it’s no longer functional.
• Bio media: Being cautious is imperative when cleaning bio-filter aquarium media. After all, these filter media types are home to beneficial bacteria. Protect this bacteria by carefully dipping it in the water.
• Mechanical filter media (sponge or filter pad for fish tank filters): It’s an entirely different approach than bio media. You don’t have to hold back, as mechanical filter media for aquarium tanks will need to be wrung out with some force. Do it multiple times because it collects dirt and other substances recklessly.

How long do aquarium filter media last?

The longevity of aquarium filter media will differ based on various factors. But I can provide a general outline for each specific type:

• Chemical filter media: Owners can expect to change chemical filter media about every two months when used regularly. Many users on Reddit have praised how this simple practice can improve the conditions of their fish tanks.
• Bio media: Bio media offers much more longevity since it never needs changing. You’ll only need to clean it carefully to ensure it’ll remain helpful.
• Mechanical filter media: This last one is more reusable than chemical filter media. It’ll last up to 6 months with routine cleaning and usage

How to change filter media in aquarium?

Step 1: Leave the old filter in place and run another tiny filter alongside it for approximately 30 days. The reason behind this is that this could provide enough time for the current filter to be settled with good bacteria. But you need to keep an eye on the flow brought about by the filters.

If these form extreme flow that disrupts your fish, then turn down the filter’s settings or you can hinder the filters using filter pads.

Step 2: Place the media from your former filter into the current filter. This is where plenty of good bacteria dwell. This would only successfully operate if the filter media comes with the same shape and size for both filters. This is not advisable if the filter media is breaking down.

Step 3: Position the media from your former filter in the aquarium beside the current filter. This shall enable the current filter to be inhabited by good bacteria. Then, after 30 days or beyond, you can lift off the former filter media.

How to care & store?

Maintaining the filter media is the most substantial thing you can execute to keep the tank in good condition. Harmful levels of nitrate, ammonia and nitrites can instantly accumulate in the tank water if the filter media malfunctions. This could lead to making your aquarium pets and plants becoming ill or even perishing.

So, it is a must to clean the filter media by giving it a thorough rinse using old tank water. You can utilize a tiny sponge, brush, or filter floss to tidy the impeller’s inlets and outlets.

Moreover, it is also practical to examine your tank water on a weekly mode with the use of testing strips. In so doing, you can monitor the different water parameters. And, when you observe some changes in the test results, then that means it is high time to clean the filter.

If the rate of flow slows down, then this may imply that the filter media is being clogged, so it is really necessary to clean it at once.

If not in use, keep it in a box; store it in a cool, dry and safe place for future use.
