Buyers’ Guide

Do I need a filter for my 10-gallon fish tank?

Let us make this clear once and for all: You’ll need a filter inside your aquarium as long as you have fish inside it; the size of your aquarium does not matter. 

The reason why this question is commonly asked is because many aquarists tend to think that having a small aquarium means that a filter isn’t that necessary and they can just keep their 10-gallon tank clean by performing regular water changes. The truth of the matter is that smaller bodies of water actually require a filter much more than larger bodies of water. This is due to the fact that smaller bodies of water tend to become concentrated with fish waste and other types of waste much more quickly. They require more attention in order to stay clean, whereas, in a larger body of water, it takes a long time for it to become concentrated with fish waste to the point where it would be harmful to fish. 

So, in conclusion, no matter how small your aquarium is, it definitely needs a filter. A filter is not an optional piece of equipment, it is absolutely needed in all aquariums in order for them to run successfully. 

What are some factors I should consider when buying a filter for my 10-gallon fish tank?

Here are some factors to think about when purchasing a filter for your 10-gallon fish tank: 

  • Aquarium Size and Flow Rate 

The flow rate of your filter is oftentimes the most important aspect of it that all aquarists need to look at before buying a certain filter. Buying a filter with the appropriate flow rate is important because buying one that has too low a flow rate will cause the filter to perform inadequate filtration inside your tank whereas buying one with too high a flow rate would cause it to create currents inside your tank that would be too strong for your fish. Hence, a balance must be struck. 

In the case of a 10-gallon tank, having a filter that has a flow rate of somewhere around 40 gallons per hour is appropriate. Please note that this number can vary by 10 – 20 GPH without you running into a problem. 

  • Price 

Filters can get quite pricey depending on how powerful they are. In the case of a filter for a 10-gallon fish tank, you’re not going to need a filter that’s too powerful so it’s a good idea to get one that’s reasonably priced.

What are the different types of filters I could opt for for my 10-gallon fish tank?

For a 10-gallon fish tank, filters such as HOB filters and fully submersible filters are most ideal. If you’re going to opt for a filter that is placed inside the tank then you should get one that’s small in size as you don’t want too big a filter crowding the inside of your 10-gallon tank. 

Since a 10-gallon tank is relatively small, you can get away with having just a sponge filter inside it which performs both mechanical and biological filtration but not chemical filtration. In this case, you would have to make up for the lack of chemical filtration manually by adding water treatments to your water regularly. 

How do I mount my filter onto my 10-gallon fish tank? 

Depending on what type of filter it is and the manufacturer, the method of mounting it onto your aquarium may vary. 

Most filters that get mounted directly onto your aquarium such as HOB filters usually come with clamp mounts that you can tighten around your aquarium wall in order to secure them. 

Submersible filters generally cup with suction-cup mounts that are able to secure them in place by being mounted onto the inner side of your aquarium’s wall. 

Where should I mount my filter in my 10-gallon fish tank?

Again, this depends entirely on the type of filter you have. Most HOB filters are placed in one certain corner of the aquarium where they are partially submerged in the water. Most submersible power filters or sponge filters are usually found at the bottom in one corner of the aquarium. It’s a good idea to place your filter in a location where it can circulate water fairly well. Another thing to think about is to place it in an orientation that enables you to hide it using an aquarium plant or an ornament, etc. 

Frequently Asked Questions (FAQs)

Is it possible to over-filter a fish tank? 

No, over-filtering a tank is not really a possibility. Having a tank that’s too clean isn’t really a problem that can have any adverse or unwanted consequences inside your fish tank. 

Can too strong of a filter kill my fish? 

Yes. If you have a filter that’s too strong for the smaller fish inside your 10-gallon fish tank then these fish may get swept up into your filter. Inside your filter, they could get cut up by the motor or impeller or any other sharp object inside your filter or they could even get stuck in the filtration media and suffocate. 

How often should I clean my fish tank filter? 

This can vary a lot depending on how powerful your filter is, how many fish are inside your tank and how much you feed them on a daily basis. When you first get a filter, it’s a good idea to keep checking every week to see when the filter needs cleaning. Once you get to a stage where the filter needs cleaning, make a note of how long it took for it to get to that stage. This will be your benchmark. 

How can I tell when my fish tank filter needs cleaning? 

A good way to tell when your filter needs cleaning is to test your water for certain increased levels in toxic materials. If your water shows increased ammonia or nitrite levels, this could be an indication that your filter needs cleaning. 

A more direct way of telling whether your filter needs cleaning is to simply look inside it and see whether there’s any clogging inside the filtration media. 

How can I keep my fish tank clean in case of a power outage?

In the case of a power outage, you can keep your fish tank clean by performing regular water changes every few hours. You can do these water changes using a small plastic cup or something similar. Please keep in mind that the water you replace the old aquarium water with always needs to be treated with a dechlorinating and a water-conditioning agent before it’s added to your aquarium. If you have it available in your home, then it’s a good idea to add a small amount of aquarium bacteria supplement to the water as well. 

Can my fish die if I turn my filter off? 

Yes. When you turn your filter off, the nitrifying bacteria inside your aquarium start dying within 30 minutes of you turning it off. These nitrifying bacteria play a very important role in neutralizing ammonia and nitrites in the water which are extremely toxic to fish. If you don’t turn your filter back on then these bacteria will continue to die and within 48 – 72 hours, your aquarium will be left with no nitrifying bacteria inside it. As a result, ammonia and nitrite levels will rise and your fish will succumb to their toxic environment. 

How long can fish survive without a filter? 

As we mentioned earlier, it takes about 48 – 72 hours for all the nitrifying bacteria inside an aquarium to die when a filter is turned off. However, we strongly recommend that you don’t let your fish go without a filter for any time longer than just a few hours. Letting your fish live in an aquarium without a filter for more than a day can definitely lead to diseases and abnormalities which could be irreversible. 

How long do fish tank filters normally last? 

Reliable filters that are bought from reputable brands can last for many years if you take care of them properly. Just be sure to clean it and lube the impeller and motor regularly and your filter should last you for many years. 

What can I do If my fish tank filter is making too much noise? 

First thing to do is identify the source of the noise. 

More often than not, the noise is due to a large, solid piece of waste stuck within your filter’s mechanical filtration media. You can easily fix this by pulling up the filtration basket and removing whatever that solid piece is. 

Another thing you can do is to lube the impeller and motor of the filter so it runs smoothly. 

Are under-gravel filters effective?

Undergravel filters used to be quite popular back in the ‘90s but they’ve quickly fallen out of popularity because it’s been conclusively proven that they are much less effective at cleaning aquariums than other types of filters such as HOB, canister and power filters. 

Final Verdict 

Almost all aquarists understand the importance of a good filter and know that if you don’t get an appropriate filter for your tank, it can interfere heavily with the successful running of your aquarium. 

After months of testing, we’ve concluded the XY-2831 Air Pump Sponge Filter to be the best filter out of all the ones we tested. It’s lightweight, has a small footprint, is inexpensive and does its job incredibly well. 

And with that, we’re at the conclusion of our post for the best filters for 10-gallon tanks.
