There might not be an easy way to estimate the actual weight of a fish tank of whichever size, especially one with accessories like heaters, filters, hoods, lights, and lids.

Even so, you can be able to tell the average size of a fish tank given the dimensions or capacity.

For instance, a 10-gallon fish tank with dimensions 20" by 10" by 12" will have an empty weight of about 11 Lbs and a filled weight of at least 111 lbs, considering water weights anywhere 8.34 Lbs per gallon.

But if you add the weight of other accessories, including bulky objects like rocks, gravel, and caves, your 10-gallon fish tank will be a lot heavier than 111 Lbs.

Having said that, if what worries you is moving your 10-gallon, you need not worry because an empty fish tank is easy to carry. But I would not recommend transferring a filled aquarium

Please read on for more insight on 10-gallon aquariums in due regard to weight, dimensions, and moving them.

10- Gallon Fish Tank Size, Weight, and Dimension

As I’ve mentioned above, the weight of an average 10-gallon fish tank is correlated to the dimension. But by industry standards, it’s considered a small (mostly beginner) measuring anywhere between 20" x 10" x 12" and 20.25" x 10.5" x 12.5".

In terms of design, 10-gallons are equally limiting with almost all tanks coming rectangular in shape.

As such, though the weight of a starter aquarium might vary, certainly not too much since the filters, heaters, lights, and decorations useable are also pretty lightweight.

Overall, I would not expect your 10-gallon fish tank to weigh more than 125 lbs regardless of what you put in it.

The average is anywhere from 110 Lbs for a bare bottom unit such as a breeder tank to about 12O Lbs for an aquarium housing a single betta, lightly decorated and accessorized.

10-Gallon Fish Tank Stand

One reason you might want to know the weight of your 10-gallon fish tank is to access what would be a good stand for it.

Well' it turns out even though you cannot move a filled 10-gallon, anything from a sturdy dresser to a hardwood cabinet can act as a stand for your tank.

As such, it’s not a must you invest in a custom stand when you are starting out. But you still want to access the structural integrity of your base to make sure every joint and hinge is still together.

Also, make sure the stand is steady and on even ground since any kind of movement exerts extra pressure on your aquarium glass and may cause it to crack.

Your ten-gallon tank would be appropriate on any solid stand or piece of furniture that has the same measurements, as long as it has four legs and is in good condition.Michelle Lynn Isle

What is The Best Filter for a 10-Gallon

Considering a 10-gallon is a relatively small fish tank, most filters in the market will work. Any sponge filter would be my first pick because of the relatively low flow rate, plus they are cheap and easy to use even for beginners.

Sponge filters are especially useful if you need to use your 10-gallon for breeding, quarantine, or to raise fry and other fragile aquatic animals like shrimp.

A small HOB unit will work as well, though power filters tend to make a lot of undesirable waterfall noise, plus they can be a little too powerful for fishes like betta that like a low water current.

That said, if you still decide to use a HOB filter on your 10-gallon, I recommend going with a Fluval Aqua Clear, which moves a lot of water enough even to clean a 20-gallon, and the unit is also simple to clean, reliable, and affordable.

Does a 10 Gallon Aquarium Need an Air Pump

It is necessary to ensure that your fish tank is well aerated, more so if you have a deep aquarium with bottom-dwelling fishes that rarely swim to the surface for air.

The best way to do this is by adding an air pump with air stones to increase surface agitation and improve the circulation of oxygen in your fish tank.

That said, an additional air pump is not a must in small fish tanks like 10-gallons, especially if you are running a filter unit that makes a powerful current like a HOB unit.

The water movement created by the filter is enough to fix enough oxygen into your aquarium sufficient for your fishes unless your setup is overstocked.

Adding live plants in your 10-gallon also helps improve the oxygen levels in your fish tank.

If you still need to use an air pump to aerate your 10-gallon fish tank (other than the one running your filter), I recommend going for something small but reliable such as this Tetra Whisper air pump.

What is The Best Heater for a 10 Gallon Tank

When keeping tropical fish, another item (away from a filter) you will be concerned about and need to consider is an aquarium heater. Luckily, once you know what size will work, choosing a unit is pretty simple.

A good rule of thumb to follow is 3 to 5 watts of power per gallon of water you have. As such, you will need anywhere from a 30 to 50 Watt heater for your 10-gallon fish tank. A 75 to 100 Watt heater will also work coupled with a timer to switch off when the temperature gets to a preset setting

What Size Hood For a 10 Gallon Tank; Lid Dimensions

Aquarium lids and hood are more than just decorative parts of a fish tank. They also serve several purposes that are important to keeping your water safe for the fish.

As such, it is a good idea to purchase a hood for your fish tank regardless of the size, 10-gallon aquariums included.

When choosing a lid for your 10-gallon, the only dimension to be concerned about is the length and the weight. You need to make sure the cover matches your tank.

So, for an average-sized 10-gallon, a lid a few points above 20 inches in length and 10 inches in width should be sufficient. Because if you go lower, the cover won’t fit, and too high, it won’t be tight enough.

To know precisely how big of a lid you need, you can also measure your tank’s length and width to make sure you are within a few points of an inch of the actual size.

In terms of the lid to get, I recommend a glass hood if since they are readily available and easy to install and operate. Some even come in a canopy style with a light fixture attached to it.

You can also get a fully custom hood, but for a small fish tank like a 10-gallon, it would be a little overkill. You should save your buck for when you get a bigger fish tank.

That’s all.

Happy 🐠🦐fish keeping, see you on the next one.
