If you have determined to have an aquarium in your house or office, there are certain important things to consider. One of them is which tank filter to choose.

If you have large fish or a reef tank you must choose a filter that provides higher flow rates. Remember this. Betta tanks, aquariums with small fish, baby fish, or live plants, in the meantime, do better with slower flow rates.

And other filters require minimal maintenance, which is better for busy aquarium owners. Take this feature into consideration when selecting a fish tank filter.

We can’t but love this Penn Plax canister filter for its reliability power, and versatility. If you are looking for a good filter for your large fish tank, Cascade 1000 will meet your expectations.

This waterfall filter not only purifies aquarium water but also creates a nice visual effect. Though it is marketed as a turtle aquarium filter, in fact, it can be used in any small (up to 40 gallonы) fish/turtle/reptile water tank. Unlike canister filters, it is mounted inside the tank, which makes it much quieter. It offers two fix modes to choose from: suction cups and a hang-on mode. The filter is compatible with various types of filtering media.
The filter is definitely worth its money. While being compact, quiet, and easy to use, it provides a decent quality of water purification. We love its compatibility with all types of media. The initial media pack includes four bio balls, which is also great. While suction cups seem strong enough, the same can’t be said about the hanging clip, which can’t hold a working filter well.
This medium-sized canister filter by Marineland comes in three sizes: the largest one with a capacity of 360 GPH can handle saltwater and freshwater aquariums up to 100 gallons in size. The filter provides a 3-stage water filtration (mechanical, chemical, and biological). A valve block helps stop the water flow quickly when needed.
All in all, this Marineland filter is a good filter for the money. It has large and convenient trays for filtering media. While providing a good flow rate, the filter is quiet enough. That being said, the suction cups are of poor quality, as well as the upper plastic tube, which seems cheap and flimsy. The plastic bio-balls included in the supply package are disappointing too.
What Boxtech offers is a mini hang-on filter for tiny aquariums of up to 10 gallons in capacity. This is a three-in-one device with the additional features of skimming and water aeration. It comes with a valve that lets adjust the flow rate. Despite its small dimensions, the device provides a decent three-stage filtration, making the water pure and aerated.
Though the filter is all-plastic, it is surprisingly well-made and durable. It is absolutely quiet, which makes it perfect for using at nighttime. Beware that it doesn’t fit the tanks with a plastic rim. In our opinion, there are serious flaws: due to its small size, the filter pad gets clogged too quickly, and the filter doesn’t restart automatically after the power outage.
Performing constant maintenance on your fish tank’s equipment is sure to enhance its performance and lifespan. Adhering to the original manual provided with the filter, you will know both how to set up a fish tank filter and how to take proper care of it so that your aquatic environment is healthy and your fish thriving. Here are important recommendations about cleaning fish tank filter.
The primary component of appropriate aquarium maintenance is water change. You should change the water (not more than 15% ) of your aquarium every two weeks. The issues how often and how to clean a fish tank filter depend primarily on the filter type.
The regular maintenance of a system of mechanical filtration implies the cleaning of the pads or sponges from the debris collected. The cartridges are to be washed only in the aquarium’s water so that the beneficial bacteria is not reduced. How often this should be performed is determined by the stocking level of the aquarium and the nitrates present in the system. Generally, once a week will be enough.
The most widely used chemical media is the activated carbon. It not only removes any unpleasant odor or coloration of your fish tank water but also effectively absorbs all the medications and dissolved organics. Activated carbon preserves its efficacy within a month or two.
Once you have implemented a mechanic and chemical filtration, a biological media should be placed to keep the water free of harmful nitrites and toxic. This is highly important.
Prior to applying extra chemical and biological filtration, you need to clean the filtering equipment you have in your aquarium. This includes removing the impeller and cleaning it and the impeller housing from all the debris stuck. Other parts of the filter involving the pipes (both intake and outlet), housings, and the body are to be carefully washed.
Buying a fish tank filter, you must have faced certain drawbacks to cope with. Our extensive FAQ will help you find answers to the most common questions nearly all novice aquarium owners have.
A: Before you install the cartridge into the filter, make certain you have turned it off. After this, take the cartridge and place it into the slot designed for it: if you have a dirty gross cartridge in it, place it in the filter reservoir and keep it there several weeks. Switch the filter only in the end.
A: The price of a fish tank filter depends on several aspects – the water flow rate, the functionality (filtration types carried out), the type of the filter, and the capacity of the aquarium. Prices range from around 15$ up to $200.
A: A fish tank filter can be used until it is one piece with no broken parts. A quality filter will serve years under the condition you deliver proper maintenance. It’s the cartridge of the filter that needs a change when it becomes too dirty.
A: The fish tank filter tubes are to be cleaned with hot water (not boiling) that must run through the tube: make certain you wear gloves and use a towel to hold the hose. Remove the tube from the aquarium and take it to a sink. Use commercially available cleaning devices: these are long wires with brushes fixed to their ends. After having pushed one through the tube and passed it several times to clean the tube, rinse with hot water again to get all the loosened gunk out the tube.
A: Where you must put the fish tank filter depends on its type. Under-gravel filters must be placed into the tank right under the gravel in a well-fitted position before you fill the tank with water. External and internal hang-on filters are to be mounted on the tank wall, whilst canister filters can be laced near, above or below the tank.
A: You can keep your nano or small aquarium without a filter, but will have to change the water every week. This is not recommended, although. Poor unfiltered water in an aquarium will lead to infections, deterioration, and the premature death of the fish you keep. Fish tank filters create tiny ecosystems that boost the growth and health of the fish and live plants inside the tank.
A: Having both a filter and live plants in your aquarium is beneficial for its inhabitants. Plants absorb and remove all the waste of fish, the excess food and decaying materials, they create an appropriate area for beneficial bacteria to grow on. Just make certain the water flow rate is slow.
A: It’s hard to give an exact answer, as it depends on several variables: the volume of water to handle, the number of fish, and fish type (some species are more demanding to the quality of water). However, there are some general recommendations. Firstly, it’s impossible to overfilter water. It means that a more powerful filter is always better than a less powerful one. Secondly, if possible, try to get two filters instead of one. Thirdly, consider the manufacturers’ recommendations but don’t take them as the gold standard. Thus, it’s OK to buy a filter rated for 50 gallons for a 30-gallon tank.
A: It is possible yet not recommended to turn a fish tank filter off at night. This tool is crucial for the health of the fish. Some types of fish produce much waste, while other types of fish deplete the oxygen level quickly. If you shut down the filter for hours at a time, that will definitely lead to serious problems with the oxygenation and cleanness of the tank water. Additionally, turning off the filter means depriving the microbes, so essential for the health of the fish, from oxygen.
As you must have learned from this article, there are different fish tank filter types to choose from. Which you pick up eventually depends on your specific requirements and expectations.
