The 6 Best Filters for Axolotl Tanks – Reviews & Top Picks for 2021
1. Penn-Plax Cascade Canister Filter for Large Aquariums and Fish Tanks – Best Overall
The Penn-Plax Cascade Canister Filter is our top pick for Axolotl tank filters because of the versatility offered by this brand. We have showcased the Cascade 1000 here, but there are four other models you can choose from that work with a wide variety of tanks. This particular model works with tanks up to 100 gallons, but Penn-Plax makes filters that work with tanks up to 200 gallons large. Another great feature of this filter is that it comes with a spray bar, which is great for promoting water movement and oxygenating your axolotl’s water. Overall, customers feel that this filter is easy to clean and operate, making it a great option for people who have never had an aquarium or used a filter before.
2. Aquaclear Fish Tank Filter, 20 to 50 Gallons – Best Value
This filter is much less expensive than other options on this list, but that doesn’t mean it is less effective. This is a hang on back (HOB) filter, which means exactly what you think: it hangs on the outside of the aquarium. This type of filter has a few benefits: firstly, it’s great for beginners because it is easy to use and requires less maintenance than other types of filters. Secondly, it’s usually more cost-effective than other types of filters. This HOB filter may not perform as well as a canister filter would, but for the price, the Aquaclear Fish Tank Filter does an excellent job. If you are still concerned about performance, the guaranteed lifetime warranty should put your mind at ease about taking a chance on this filter.
3. Marineland Magniflow Canister Filter For Aquariums – Premium Choice
If money is no object, you may want to consider splurging on the Marineland Magniflow Canister Filter. This filter comes in three different sizes for tanks that range from 30 to 100 gallons large. This filter is extremely quiet, which means it won’t bother you as it works. The Marineland Magniflow Canister Filter also features not three, but four stages of filtration, meaning your Axolotl’s water will be as clean as possible if you use this filter. Like some other canister filters, the Marineland Magniflow Canister Filter comes with many different parts that can make it somewhat difficult to install.
4. Fluval 107 Performance Canister Filter for Aquariums
The Fluval 07 series features a design that was created to make the filter quieter and more energy-efficient than previous iterations. According to Fluval, the 107 model uses just 10 watts of electricity, which is about equivalent to one LED light bulb. Customers note that the canister is so quiet they don’t even realize it is on. One drawback to this canister filter is that it does not come with a spray bar; although this filter is already pricey, we recommend purchasing the spray bar as well if you are planning to buy one of these filters.
5. Polar Aurora External Aquarium Canister
The Polar Aurora External Aquarium Canister comes in four different sizes. The largest model can accommodate tanks up to 200 gallons large. It’s more all-inclusive than other filters in that it comes with both a spray bar and the actual filter media. It also comes with an easy-to-use self-priming pump that you can operate simply by pressing a button. Customers note that this filter is fairly difficult to put together, but as long as you put it together correctly, it should work beautifully; this filter is tried and tested by many aquarium owners who approve of its quality.
6. SunSun HW-404B 525 GPH 5-Stage External Canister Filter with 9W UV Sterilizer
The SunSun HW-404B filter is another great choice for larger tanks up to 150 gallons. With four stages of filtration, this filter has the ability to keep your axolotl’s water as pure and clean as can be. Its large media baskets mean that you have a lot of flexibility as to what type of media you would like to add to the filter. In addition to its four-stage filtration system, this filter comes with a UV sterilizer that has the ability to kill bacteria that are harmful to your axolotl. Similar to other canister filters, you may not want to purchase this filter if you are brand new to keeping an aquarium; the instructions for setting up this filter are not very clear.
What To Look For When Buying an Axolotl Tank
As axolotls are aquatic animals, you need to purchase a tank that will be adequate for their needs. In this buyer’s guide, we will discuss what to look for when purchasing a tank for your axolotl, including minimum tank size, tank material, and set up.
Minimum Tank Size
The tank you purchase for your axolotl should be at least 15 gallons large. Although the axolotl itself only grows to be about 9-12 inches long, they produce a relatively large amount of waste and require a tank with large floor space. These salamanders are also known for sometimes jumping out of their tank, so you need to make sure the lid is secure.
If you have more than one axolotl, you should plan to purchase a much larger tank. Two axolotls need a tank that is about 55 gallons large.
When you are looking for your axolotl tank, another consideration you will need to make is the durability of the tank. You should search for glass tanks that are at least a quarter-inch thick in order to make sure that they will be able to withstand the water pressure in the tank and prevent any cracks from forming. This is particularly important if you are buying a larger tank.
In addition to the tank itself, you will need to think about purchasing filters, lights, plants and other decor, and chillers. In some cases, it may be easier to purchase a tank kit that comes with all of these accessories. That way, you don’t need to worry about purchasing the right type of accessories for your tank.
Things to Consider When Purchasing a Filter
Once you have your tank, you need to purchase a filter for the tank. As stated, axolotls produce a large amount of waste, so you are doing yourself a favor by purchasing a filter. Otherwise, you will need to change the water out very frequently to make sure your axolotl stays healthy.
Most of the filters on this list are canister filters because although they are more difficult to maintain than other filters, they are also one of the most efficient types of filters out there. They also frequently come with spray bars, which help improve the oxygenation of your axolotl’s tank.
Make sure the filtration rate remains relatively slow. If the current is too strong, your axolotl can become stressed. When you are choosing your filter, look at its filtration rate in GPH (gallons per hour). Generally speaking, you should buy a filter whose GPH is about four times your tank’s capacity. If your tank’s capacity is 30 gallons, for example, you should look for a filter with a GPH of 120.
The Penn-Plax Cascade Canister Filter stands out as one of the best options out there given how versatile and easy to operate it is. The Aquaclear Fish Tank was our value choice because, at less than half the price of other filters on our list, it still delivers on performance. As you can see from our reviews, there are many great options available if you are looking for an axolotl tank filter; we hope that you have learned something about axolotl tanks and filters and that you’ve been able to find an option that works for you.
