The Right Material for Your Aquarium

by Apr 27, 20206 comments

Have you ever wondered what types of glass are used in building our Aquariums, or are there any other materials that we can use? In this article, we will be discussing the right material for your aquarium.

Standard Glass

Regular glass is by far the most common material in making aquariums. Glass is actually manufactured by heating ordinary sand silica (silicon dioxide), the primary constituent of sand, to 1700 degrees Celsius. At this temperature, the sand will liquefy. Glass is most often manufactured by the rapid cooling of the molten form after removing the bubbles.

Ordinary glass has a noticeable greenish tint, especially when viewed from the end of the panel. But it is cheap and represents a cost-effective solution for larger tanks.

It is also scratch-resistant – this is advantageous when you have all the tools to keep that glass clean. Be it scrubbing the algae in the glass or using a razor blade (be careful not to touch the silicon seams). You don’t have to worry about the glass being scratched. It will not discolor with age as well.

However, glass is heavy, twice the weight of acrylic of the same size. This could be a serious drawback on huge aquariums. Shape and sizes are limited too.

Low Iron Glass

It uses a small amount of iron to eliminate the blue-greenish tint of standard glass, and it cost more. Please see the comparison below between standard glass at the right and low iron glass on the left.

Acrylic is 50 % lighter than glass of the same dimensions. For large aquariums, a material that offers 50 % weight reduction while retaining strength and integrity is certainly an appealing option.

Acrylic is generally stronger than glass. Additionally, the joints between acrylic panels can be chemically fused. Glass aquariums and their silicon seams cannot match this level of strength.

Acrylic is customizable and can be molded to form any imaginable tank shapes like curved, bow front, octagon, cylindrical tanks, etc. You name it, and it can be molded like that.

However, as I said previously, acrylic is very easy to scratch. This means you are very limited on tools and cleaning materials to clean your acrylic tanks. But these light scratches can be removed by employing a buffing process. Deeper scratches, on both glass and acrylic, are permanent.

Acrylic is expensive, there is no getting around it, and some acrylic types can yellow in time.

Inspect Your Tank

Carefully inspect the craftsmanship, joints, and silicon seams of your newly bought aquarium, if possible, while you are still in the store. Take pictures, and don’t be afraid to point out any flaws that you may find. You can bring a flashlight and magnifying glass to help you with inspecting.

Closing Remarks

I hope you enjoyed this article. If you have additional questions or want to share your experiences with the materials used in building your aquariums, please leave a comment below.

    Hi Lemeul,

    I like the layout fo your background and white text quite a lot. 

    I don’t think one can ever go wrong when you use your passion to assist other people and also in the process earn an income from that. After all, a lot of hard work goes into that, and in most cases, also a lot of money.

    Thank you for sharing. I wish you lots of success with the venture.

      Hello Evans, I agree aquariums, paludariums, terrariums, and ripariums are all vivariums and thank you for sharing your knowledge. I actually discussed all of these in the Paludarium style in my website.
