Best Rimless Aquariums in 2021: Reviews with Comparisons

One of the most exciting developments in the last few years in the home and office aquarium environment is the creating of rimless aquariums. For many years people believed that although having the best rimless aquariums would have been nice, it just was not possible. It was believed that the glass panes need rims to stay intact and leak-free.

However, with advancements in technology, it is now possible to omit the bracing around the top of the fish tank as well as the canopy.

The advantage of this is that it leaves the top free of any visual obstructions. It creates the illusion of an “endless” aquarium. A rimless aquarium also easily blends in with your home or office décor.

Rimless aquariums are only held together by silicon glue. Therefore you’ll find that it is the smaller aquariums that are benefitting from the rimless technology. Glue on its own is not strong enough to hold together a large tank with many gallons of water. Size definitely plays a role when manufacturing rimless aquariums.

Other material than glass, like acrylic, is also much stronger and more suitable for rimless aquariums.

Landen Rimless Low Iron Glass Aquarium

The Landen Rimless Low Iron Glass Aquarium is seen by many as one of the best rimless aquariums on the market. The tank is made from 8mm thick crystal clear low iron glass. This gives at least 91% transparency. The tank is 23.6 inches long, 15.7 inches wide and 15.7 inches in height. It weighs 43.6 pounds. It offers premium quality work on the fish tank’s silicone rimming.

When you purchase this aquarium you must keep in mind that you only get the tank. You’ll have to research what extra equipment you need and buy it separately. The items you still need include tank filters, lighting and heaters or chillers.

It is not an aquarium for the beginner. A seasoned aquarium enthusiast will know what extra equipment is needed and will know how to assemble the aquarium correctly.

The pros of this aquarium are that it comes with low iron and high transparency glass. It has clean silicon lines and you can buy the components you want.

There is not many cons, except that it is not for a beginner. One other con is that it is more expensive to build a DIY tank than purchasing a kit with everything provided. But that is not unique to this tank. It is true of every fish tank you buy without the full kit.

What do You have to Do to Start with a Rimless Aquarium?

Your first step is to decide where you want to put your aquarium. Measure the space as the length, width and height of your new aquarium have to be compatible with the space available.

Then decide whether you want to build your aquarium with a full kit, or do you want to purchase only the tank and then purchase all the other accessories separately.

What is the importance of a rimless aquarium?

You can view all the fish and the ornaments in the tank from any side. The special strong glass or acrylic sides provide a very clear view of the inside of the tank.

If you think of your aquarium as a work of art that must enhance the décor of your room, a rimless aquarium is what you need.

How will I maintain a rimless aquarium?

In principle, you maintain a rimless aquarium exactly as you would maintain an aquarium with a rim. However, if you have a saltwater aquarium there is one extra aspect you must attend to regularly. The saltwater can cause a dark ring at the level of the water. To keep your aquarium beautiful you’ll have to clean the top part of your tank regularly.

Most rimless aquariums also don’t have a top lid. You have to check every day for things that could have climbed or jumped into your fish tank.

Some articles can also be blown by the wind into the aquarium or someone could’ve accidentally dropped something into the tank. When you spot something, take it out of your aquarium.

To enjoy the beautiful appearance of a rimless aquarium, this little bit of extra work is worthwhile!
