Best Filter For 30 Gallon Fish Tank

When it comes to fish tanks, they all need filters. Some people might tell you that this fish or that fish does not need the aquarium to have a filter. However, that just is not true. A fish tank, especially a larger one like a 30 gallon tank, needs to have proper filtration in order for the fish to be healthy and survive.


Without a good filter, you cannot expect your fish to remain in good condition. After a while, they will most likely perish. We are here today to help you find the best filter for a 30 gallon fish tank (this is our top pick) and we have narrowed it down to 5 options.

The Best Filter For 30 Gallon Fish Tanks: Top 5

We have put together a list of 5 decent filters that we feel are ideal for 30 gallon tanks, even though they are all a little different, each of them makes for a really good choice in their own way.

Let’s take a closer look at each of our top 5 picks in more detail, starting off with our top pick;

1. Penn Plax Cascade Canister Aquarium Filter

The Penn Plax Filter is definitely a fan favorite, and one of our personal favorite options as well. This is true for a variety of reasons. This particular filter is ideal for any aquarium up to 30 gallons. It can handle 115 gallons of water per hour.

This means that it can filter the entirety of a 30 gallon tank almost 4 times per hour, which is quite impressive to say the least. On that same note, what is also impressive about the Penn Plax Canister Filter is that it features a fairly durable build with a solid outer shell.

This filter does come with rotating valves that you can use for flow control, which is convenient because you can match the rate of filtration to the needs of your aquarium. The flow valves can rotate a full 360 degrees, which makes it a convenient option for even the tightest of spaces.

While the filter itself is not necessarily small, it won’t take up too much space. You might also like how the Penn Plax Cascade Canister Aquarium Filter has an easy off top and easy to handle tubing, thus making maintenance and cleaning about as easy as can be.

Something that we really like about the Penn Plax Aquarium Filter is that it has an easy prime feature. You literally just need to push a button to totally prime this bad boy, making life just that much easier for you.

This filter is that it does engage in all 3 major types of filtration including mechanical, biological, and chemical filtration. It comes with 2 massive media baskets that you can customize with various types of media to suit the needs of your aquarium to a tee.

This particular filter is another really good choice to go with for a 30 gallon aquarium, or anything slightly smaller. Actually, this filter can be used for any aquarium up to 50 gallons. This thing has a massive flow rate of 200 gallons per hour.

So, if you use it for a 30 gallon aquarium, it can filter the entirety of the tank almost 7 times per hour, which is of course extremely impressive. Of course, the AquaClear Power Filter also allows for flow rate control, so you can set it at the ideal filtration level for a 20 gallon tank or a 50 gallon tank too.

One of the things that we really like about the AquaClear Power Filter is that it is a hang on back filter. This means that it barely takes up any space at all inside of the aquarium, thus reserving prime real estate for your fish and plants. On that same note, this thing is also very easy to install.

There are only a few pieces that you need to put together, and using the built in clamps, you can easily attach it to the rim of your aquarium. Furthermore, the design of the AquaClear Power Filter is great because it is also fairly easy to clean and maintain. Filters do need quite a bit of maintenance, so this is quite important.

One of the things which this filter is known for is being fairly quiet, something that both you and your fish can appreciate. Also, the AquaClear Power Filter does not use very much energy, something that bodes well for your electricity costs. This filter does engage in all 3 major types of filtration including mechanical, chemical, and biological.

3. Marineland Penguin Power Filter

This is another hang on back filter option that we think is a great fit for any 30 gallon aquarium. Like we said before, we do like hang on back filters because they don’t take up room inside of the aquarium nor do they need shelf space. Simply mount it to the rim of your aquarium and it is good to go. Not taking up room inside of the aquarium itself is something that we always look out for.

The Marineland Penguin Power Filter is also fairly easy to mount and set up. Simply use the included clamps to mount it on the rim of the tank. Once you have connected the tubing and inserted the media, it is good to go. People also tend to like the Marineland Penguin Power Filter because maintenance is not hard to perform on this thing. When it is closed, it is completely secure, but getting to the inside to perform maintenance is about as easy as it gets.

The Marineland Penguin Filter can be used for aquariums between 20 and 50 gallons in size, which is more than ideal for a 30 gallon tank. Just like the previous filter we looked at, this particular one has a flow rate of 200 gallons per hour. In other words, it can process all of the water in a 30 gallon tank more than 6 times per hour for some really clean and clear water. The flow rate is adjustable, so you can increase or decrease the flow rate depending on the needs of your aquarium.

Finally, the Marineland Filter does all 3 types of filtration with ease, chemical, biological, and mechanical. It comes with all kinds of media included, which includes a patented noise reducing bio-wheel and activated black diamond carbon. Removing all manners of contaminants from the water, while also being fairly quiet is something that the Marineland Power Filter definitely does without question.

  • Adjustable flow rate.
  • Easy to mount and install.

As the name of this filter implies, the Tetra Whisper Power Filter is one of the quietest filters you can get your hands on right now. Nobody likes a noisy filtration unit, a problem which this particular model does not suffer from. The fact that this filter is so quiet is indeed one of its biggest selling points.

Now, this is also a hang on the back filter, which means that it is mounted on the rim of the tank.

It is a great 3 stage filtration system with simple 3 in 1 cartridges that make life a whole lot easier.

The Whisper Power Filter is designed to be used with a 30 gallon tank or anything smaller than that. It has a decent flow rate and can filter all of the water in your tank several times over per hour. It may not have quite as high a flow rate as some other filters, but it is more than good enough for a fairly well-stocked 30 gallon tank. In fact, you can change the flow rate depending on the filtration requirements of your particular aquarium.

  • Easy to install and maintain.
