What is a Rimless Fish Tank

Different design

Aquariums were mostly created equal until some companies decided to design the tank differently to offer different options, features, and general overall look.
One of these new designs was to omit the bracing and canopy and leaving the top part free of any visual obstructions.
This provides a very sleek and natural look.
This type of tank tends to blend better in an environment, be it in a home or in an office. The dark canopy tops that come with the regular tanks are an eye sore and can be a distraction to the life inside the tank.

Rimless tanks are a great addition
to any type of interior design.

They are usually on the smaller capacity side and usually don’t come with a stand.
This is a great choice for those of us that want to have options about our aquarium placement and general look and design of our stand.

Rimless Tank Feature

The traditional aquariums have a top and bottom black bracing system that solidifies the tank.
The quality of the glass used in these aquariums is not as high as the rimless tanks and need more weight support.
This is the main feature that differentiates the regular tanks and the rimless tanks.

Top Quality Glass

The glass that is used in the rimless tanks is usually thicker and better quality.

It has to support the weight of the water because of the lack of bracing.
This glass is usually clearer than the typical aquariums, giving them a purer look without the green hue that is sometimes in the cheaper regular glass tanks.
They achieve this because of the low iron content when producing the glass.

Here is a video describing the different types of glass and acrylics used for making aquariums today.
Each type of tank has special features like some being less costly, some weighing less, others being easily surface scratched.
The low iron glass that is used in the rimless tanks has one of the top clarity features, but is also costlier then the regular glass.

Who is a Rimless Tank For

Experienced Aquarists

These tanks are usually sold without the accessories like filters and lights.
They need to be purchased individually so obviously this means that you need to do a lot of research beforehand.
Rimless tanks are recommended for the intermediate or experienced aquarists.
It is said that this type of tank is recommended for the more experienced aquarists, but like most things, if you prepare, research and know what you are doing, then you can still go this route even if you are a beginner.
There are a few rimless tanks that are sold with accessories and we will review a few in this article.

Beginner Hobbyists

You can still purchase one of these if you are a beginner but just keep in mind that you will need to do much more research and spend more time preparing and setting up the tank if you purchase one that is not sold as a kit.
The all-in-one kits are great for beginners and are usually easy to set up and are virtually hassle free.
This is the reason why beginners go for these kits in the first place.
Starting off with difficulties and challenges will increase the chances that you will abandon your hobby early on.
It may sound obvious but making an easy and gradual start will provide confidence and motivation to grow with your fish keeping hobby.
If you are just starting out, here are some more information to help you choose your first fish tank.

Design Buffs

If you are keen on having a sleek tank and if you prefer to have a natural looking aquarium that has a smooth clear look, then the rimless tank is the way to go.
If your home or office has a modern look and feel, then a rimless tank will definitely fit your environment very well.

Smaller Tanks

These tanks are normally sold on the smaller capacity side.
Given the nature of the accessibility from the top without the canopy, the larger aquariums possibly stand to have more debris and exterior undesirable factors affecting the water and the inhabitants.

How to Choose a Rimless Fish Tank

There are several types on the market today.
Most come solo and have to be accessorized with filters, lights and other fixtures and decorations.
There a few all-in-one kits on the market today and we will review a few of these for you should you want to purchase an easy to install and hassle free aquarium.
Otherwise, you will choose the tank that best suits the allowable space in your environment and, of course, the one that fits into your budget.

Getting the bigger aquarium is always a recommended thing, as the smaller aquariums tend to require more maintenance to keep water levels healthy and stable.

How Does Rimless Fish Tank work

These tanks are mostly purchased for their sleek and attractive look.
Once set up with filter and other fixtures, the aquarium works just like any other regular braced tank with canopy.
They offer a greater visual experience as there is no distraction from the braces and canopy.
You will have to monitor more than with a regular tank for possible external debris getting into the water.

Advantages and Benefits of a Rimless Tank

Sleek Look

The look of the rimless tank is very striking.
It offers a sleek visual and a natural feeling.
The glass is iron free, the clarity level is quite high and they don’t have the green tint that is found in the regular tanks.

When the water line is visible at the top of a tank, we get the natural habitat feeling.

The distraction of the canopy top is not present and the eye of the viewer stays focused on the fish and the contents of the tank.
These tanks are made of thicker and better quality glass so they look even more elegant.

Choose Your Accessories

If you are a more experienced aquarist and opt for a rimless tank, then you probably won’t be too tempted by an all-in-one kits.
There is absolutely nothing wrong with the kits, but with these kits you don’t get to choose the accessories and fixtures yourself.
Being a more seasoned hobbyist means that you have done some research and have some experiences with previous aquariums.
This way, by purchasing a rimless tank, you will have your perfectly designed aquarium exactly to your liking.
Having tried and tested things in the past, your style and likes are more pronounced.

Disadvantages of a Rimless Tank

Jumping Fish and Straying Snails

Being that the tank has no top, the inhabitants have to be carefully selected.

Fish that are prone to jumping and snails that travel a lot cannot be placed in this type of aquarium.

You may wake up with evaded snails and countertop stranded fish.

Water Spills

You also will have to face the occasional water spill.
The canopy tops assure that any type of splashing, either form the inhabitants, filter or by the owner will stay inside.
There is a higher risk for some of the water to end up outside the tank.
This is not a big deal but needs to be taken into consideration depending on which surface the tank is going.

Creeping Salt

The saltwater aquariums tend to produce salt residue build-up at the water line and this may create an unpleasant look and will need to be maintained regularly.
Regualr scrubs will be necessary, more then with a canopy top aquarium that can easily hide the salt line for a longer period before you wash it.

Things to look for

Glass Thickness and Quality

The glass should be a decent thickness to support the weight of the water without the regular braces.
Make sure that it is the highest quality possible for your budget.
The glass used in the rimless tanks usually contain low iron to assure the clarity and transparency of the glass.
Make sure to look for low iron content and high clarity percentage. Anything over 90% is a good buy.

All-in–one kit

You will get the rimless beauty, but also have the necessary accessories that go with it to get you started.
This will minimize your shopping and selecting time, but remember that you don’t get to choose the fixtures you may have wanted to achieve the look you want.
