How to Make an Aquarium Tank

In my previous post, I listed the reasons why you should make your own aquarium tank. Now, I will show the step-by-step procedure of making your own aquarium tank. You will need a hand (I mean someone to help you :p) since glass is delicate, you would not want to break it.

a. Measure. Bring the tape measure or ruler, and measure the size of the table or place where you will put the aquarium.

b. Glass. Get the measure of the glass you need before you head to the store. Here is the best link that provides calculator to measure every side of your tank.  Hint* Based on my experience, keep an extra space similar to the thickness size of the glass in the base. This will make sure that the sides will fit properly.

c. Buy glass, silicone and silicone gun, styrofoam, and strings. Make sure that the silicone you bought is for aquarium use. There are some silicone that are not for aquarium so read the fine print at the back of the tube, it should be mentioned there that it can be used for aquarium tank.

The styro foam that you need should be as big as the base of your tank. This will prevent your tank to crack and it’s easier to move the tank later. And the string will be used to hold the glasses in place after it is assembled.

d. It’s silicone time! First, put silicone on all sides of the base glass. Next, put silicone on the two vertical sides of the glass which will be the longer side of the tank (front and back glasses). Make sure that there are no blank spots when you put the silicone.

e. Assembly time! When you’re done putting silicone on the sides of the glasses as mentioned above, it’s time to assemble them. First, on the base glass, put the back side glass on the part where you put the silicone, making sure that ends are correctly placed. Next, put the two glass sides, again, make sure that silicone are holding them and the sides and corners are in place. Lastly, put the front side glass, if you measure the glass properly, it should be easy to assemble this last piece as it is like putting the last piece of the jigsaw puzzle. When you are sure that all corners and sides are properly adjusted, put strings around them and tighten them just enough to hold the glasses in place. (I was not able to take pictures while assembling the glasses because this part was quite hectic that I forgot to snap photos.)

f. Silicone again?! Yes, this time you need your forefinger. You need to fill in the corners with silicone to prevent the water from spilling. Put a moderate amount of silicone on your forefinger and run them through the inside corner of the tank. Repeat this until all base corners and side corners are filled with silicone. You may apply another coating of silicone if you think that it is too thin.

g. You’re done! Rest the tank for 24 hours and then you’re ready to use it. Make sure to clean it first before using.
