120 Gallon Aquarium – is it right for you?

Why buy a 120 Gallon Aquarium?

In simple terms, a 120 gallon aquarium holds a lot of fish if they’re smaller, but it also holds lots of Cichlids! Perfect for African Cichlids, 18” Pleco or even a 14” Oscar too!

We have a 120 gallon tank recommendation and a slightly larger 150 gallon

if you are able to go a little bigger

at the bottom of this article.

 

What to consider before buying a 120 gallon aquarium

Quality of the tank and the stand

Make sure you buy a good tank, there is a lot of water to spill if it has a leak – be careful when first filling this monster – take your time.  If you fill this slowly, not all in the same day, you will save yourself a lot of cleaning up should it have a leak.

Please refer to our setting up a new tank post here.

Being a larger tank means that you will want to invest in a sturdy stand.  Sometimes the stand and tank only come as a set – this is a drawback as often the stand may be made of particle board and is not great.  It may last, but I would want a better stand, again no water drowning the floor and fish lost because the stand collapses.  Speaking of fish – check out our article on moving up to a larger tank HERE.

Check out any reviews for the stand quality, or ask the seller – worth reading before ordering.

Warranty – limits and exclusions

The issue with most manufacturers is that they want to limit the warranty they provide – so make sure you pay attention to the detail. Most warranties cover any defects in materials or workmanship, subject to the conditions and exceptions stated below.

Usually the warranty is only for you the purchaser – you cannot pass it on if you sell the tank.  The warranty terminates if you sell or otherwise transfer the aquarium. Warranties normally are limited to the replacement of the tank only and not for property or livestock loss – so any dead fish or ruined carpets are not covered if the tank leaks.

The exclusions and exceptions to the warranty cover – particularly if you have a heavy 120 gallon tank

These are the terms that allow the seller or manufacturer to say you bought the wrong stand.  Which is amazing as often their stand is part of a set, and it is not as good as the one you may buy from somewhere else.

If the aquarium is placed on a stand that is not commercially manufactured for use with an aquarium of this size and weight, is inadequate to accommodate the size and weight of the aquarium or does not provide a flat, level surface capable of fully supporting the aquarium’s bottom frame.

So when you decide on a stand make sure it complies with the above – you may have to get proof when you buy the stand that it is suitable for the weight of a 120 gallon aquarium.

In common US measures, one gallon of water weighs 8.345 pounds.  That’s 1001 pounds for 120 gallons, (71.5 stone) plus the weight of the tank itself.  

 

Typical Aquarium Dimensions

They are great for living areas at home as they are usually rectangular.  But make sure you have a solid floor taking all that weight.  You can see above these tanks weigh a lot as well as hold a lot of fish.

  • Typical Aquarium Dimensions: 18″L x 60″W x 26″H  (46cm x 152cm x 66cm)
  • The Stand will usually be about the same size, the height maybe a little more at say 30″ (76cm) high.

  1. This seems like an awesome price for a 120 gal tank. I paid a lot more for my 88 gal tank! I’ve been wanting to get a bigger tank to put in my den, I will check this one out that you posted.

  2. Seems like a decent tank. Now all I gotta do is figure out each kind of variety of fish I will get! I guess that’s the fun part.

    • IMO it’s a great starter size… when you start out you’ll end up wanting to add more fish so might as well go a little bigger the first time.

  3. 1,000+ pounds is a lot! I didn’t realize it would weigh this much. I can see now why having a floor that wasn’t solidly built would cause an issue, even for this 120 gallon aquarium, I can’t imagine how someone could hold the 2,000 gallon fish tank! I would think that they would have to have some support from the floor under it, or have it on the bottom floor of the house. That’s wild to think of just how much this would weigh.

  4. I love my 120 gallon fish tank. But I admit that once I got that one, I wanted a bigger one! I think I’ll probably keep wanting a bigger size till my house won’t hold it.

    • I guess you need to check out the weight limits with the manufacturer – all homes are made differently! Think of it as having 4 people weighing 20 stone each sitting on a bench or seat that is about 5ft long.

  5. That’s a very helpful article – it’s very difficult to find a large aquarium from a reputable manufacturer nowadays. thank you!
