This model is part of the Crystalline of LifeGuard Aquatics. This collection of aquariums features incredibly clear glass for you to see all your fishes. However, this model is apart from the others in the product line because it doesn’t contain built-in filters. Instead, you have the complete freedom to install your own unique filters tailored to the needs of your fish.

What makes it stand out?

  • Lifeguard Low Iron Ultra Clear Crystal Aquarium Tank comes with a Quiet One submersible pump. This means you don't have to hear the noisy motor so you can watch your fish at peace.

Lastly, it comes with a bottom insulation pad to prevent the glass from getting cold and better insulate your water.

Which disadvantages must you keep in mind?

  • The only drawback of Lifeguard Low Iron Ultra Clear Crystal Aquarium Tank is that it is difficult to assemble. Using the manual is helpful, but you have to be very careful about not breaking any glass when assembling.

The 20-gallon tank is best for housing aquatic life in a contemporary setting while providing a clear view of the inhabitants within and without.

This 8mm tank sports the largest capacity in this product line. While the other models can hold between 7-15 gallons, this massive tank holds 20 gallons. Since it’s 8mm thick, it can easily and safely hold all that water, giving your fish an adequate supply of oxygen in the water, making it great for people with large marine systems.

Why are we impressed?

  • A great addition to any home, this tank is suitable for both fresh and saltwater. The rear filtration chamber provides additional support in cleaning the water, while the return tube helps maintain stability through circulating aquarium flow. With the use of bio balls, the 20-gallon capacity ensures that the tank will remain clean throughout its usage.

What negatives must you be aware of?

  • Due to the sleek design of this tank, there is no lid included. This can be troublesome when moving or adjusting objects in close proximity to the aquarium. Users must be extra cautious during these times as accidents may occur if mishandled.

Place the Aquarium on a Flat Surface

It is best to place your rimless aquarium on a flat surface because this will keep it more stable, and there will be less chance of an accident occurring. If you do not have a level surface, then it might be a good idea to invest in leveling the floor so that the water stays still and does not spill.

This is another step towards installing your rimless aquarium, and it is best to fill the fish tank with water as soon as you can after its installation. This will help remove all of the dust and debris that might have collected inside during the process of transport.

You may add any decorations that you want to make your aquarium stunning.

Adding the Light

Adding a light to your aquarium might also be a good idea since it will give the fish a more lively environment, and they will notice it immediately. This, in turn, will encourage them to roam around their new home more freely, and you will have less of a chance of seeing them hiding in one corner all day long.

Normal output fluorescent lighting, compact fluorescent lighting, high-intensity metal halide lighting, and LED (Light Emitting Diode) systems.

Adding Fish

Once you have successfully installed your rimless aquarium and added the decorations, it is best to add a few fish right away. However, if you plan on putting other creatures in it, like turtles or frogs, then you might want to wait a little longer since it can be harmful to them if they are not used to the temperature of the water quite yet.


Rimless aquariums do not have a rim around the opening, and they are usually made of glass. Rimmed aquariums, on the other hand, come with a small and visible rim at the top, and they often include plastic decorations as well.

It is best to clean rimless aquariums every two weeks or so by changing the water and removing any debris. However, if you have a large fish tank, it might be a good idea to clean it once a month since there will be more contaminants inside it.
