What To Look For When Buying An Aquarium Filter For 29/30/40 Gallon Tank?


For most beginners in the aquarium collecting community, starting out can be hard. These budding enthusiasts soon realize that things are not as simple as it seems, and that there are actually a number of important factors that are not to be overlooked. Usage, placing, noise, maintenance, these are just some of the important elements on such a long list.

There are filters built specifically for certain tank sizes, and this is important to understand for starters. This is so because they are made to utilize and work on the tank sizes they are specified for. They are not too hard or too small in the right tank, which means that they would just put out the right amount of power thus focusing on your tank’s maintenance needs.

As a seasoned enthusiast, I have taken it upon myself to create this simple list in order for beginners to have a framework of choosing the right filter for your aquarium, be it the 29 gallon, 30 gallon, or the 40 gallon tank.

The Right Size aquarium filter

One of the most basic factors to consider in buying the right filter for you, considering the size of a filter is based upon two reasons. The first reason being space. You need to make sure that the filter you choose will be able to make great work based on your aquarium’s size. For example, are you okay with buying a powerful 29 gallon aquarium, although it might be bigger in size? In some instances, the more powerful filters are bulky in size. This might affect the aesthetics settings you may designed for your tank. There are milder 29 gallon aquarium filters of course, and they tend to be slimmer in size. Would you be okay with a milder filter that would not take up too much space to affect your aesthetics?

Aside from considering the space for aesthetic purposes, you should also consider the filter’s size for the space they need for utilized filtering. There are some powerful 30 gallon fish tank filters that are to be placed under the gravel in order to maximize its work, while there are also some that are placed on the walls. If you do not want to give up swimming space for your little fish friends, then maybe you could opt for the HOB or hang-on-back type filters.

When choosing a filter, consider its size and the placing and space they will assume once placed on your tank.

The Filter’s Maintenance

The 29 gallon, 30 gallon, and 40 gallon tanks are considered by the community as the range of middle-sized aquarium tanks. Thankfully, that means that although it is quite bigger than the starter tanks of 2.5 gallon up to the 10 or 20-gallon ones, it is still not as complex as the maintenance required for the bigger tanks upwards of it. However, that does not mean that you should skip considering the filter’s required maintenance.

Owners are the ones that are putting in time, energy, and effort in the maintenance of the filters. One of the first things to look at are your chosen filter’s cartridges. Since your filters will be the one responsible for cleaning the tank from the inside, then surely it can and will get clogged up from time to time. Make sure to know if your filter’s cartridges are easy to replace or change, that way you can estimate the frequency of times when you should clean them. It is also important to take note of its durability. Now its durability is reliant on you as much as it relies on its make. Ask about the filter’s make, the materials used in it and the company that makes it. That should give you already tons of insight regarding its quality. With this, you are able to gauge how long it can last without you checking up on it.

The filter’s installation

would be important to factor in as well, because sometimes we are not able to install the filter properly as instructed (maybe because of misunderstanding of the instructions or simply making mistakes) and it proves to be damaging to the tanks and our little fish friends inside it. Be sure that you are ready to receive and grasp information correctly regarding the installation if it is a complex one.

And lastly, the priming. Here is a trick every fish tank owner needs to know: that most filters need to be primed before using it to its extent. Priming is when you place water on the filter’s pump reservoir until it is full. This is to ensure that there is no air in the filter’s tubing, because it will cause your filter to burn out quickly and malfunction. Most filters need to be primed before use, however, today there are a number of self-priming and no-prime filters available in the market for the 29 gallon, 30 gallon, and the 40 gallon aquarium tanks.

The Filtering Process

Now comes the complicated part, considering the filtering process. As it is a more complicated factors, I have broken it down to several parts.

Amount of Water Processed – It is quite important to check you filter’s maximum ability in terms of the amount of water it can process during a specific time. Let us say we are to measure it in hours, just how many hours would it take for your filter to process all of the tank’s water? It is important to know this because different owners spend different amounts of time with the tank’s cleaning and maintenance, and the filter’s process time is to be considered when making cleaning arrangements.

Water Quality’s Maintenance – Does the filter you choose have the power to maintain the amount of water in your tank clean, and for how long? Will it be working overtime just to clean the whole tank, or will it only run for a shorter period of time? The 29 gallon tanks and 40 gallon tanks can have the same water processing time, for as long as they use the specific filters built for them. And so choose the filters that are made for your tank, and after choosing that, opt for the ones that you think will help you maintain the tank’s water quality as you work with your own personal schedule.

Processing Power aquarium filter

Learning about the processing power of your filter is the key to further understanding of the filter’s process time and quality maintenance. It dictates the amount of time and energy owners should spend in cleaning the tanks from the inside.

Two minor things to consider when talking about the filtering process are the options for adjustable flow rate, and the filter’s noise. The best filter for 30 gallon aquarium tanks are nowadays equipped with options for adjustable flow rate, which makes it easier for owners to gauge the amount of time needed when cleaning the tanks as they control the flow of water filtered. And as we all know, some power filters are noisy, while some work with a subtler sound. Before choosing the filter for its power and size, take time to consider the sound it makes if you are sensitive to that area.

These are some of the most basic factors to consider when buying a 29 gallon, 30 gallon, or the 40 gallon tank. Should you look into opting for these aquarium sizes, then be sure to choose the right filter for your tank, and start off in no time!


Now that you have seen all the important information about the best filter for 29/30/40 gallon aquarium, you can now confidently purchase the one that will suit your needs. Always bear in mind, though, that these products have their specific settings and it is highly advisable that you read the instructions before plugging it in. This way, you can eliminate any kind of adverse effects to your fish and to yourself in case you have overlooked a certain step in the instructions or if the product that you received have some issues.
