When building a glass aquarium tank, your first task is to get glass panels for your tank. For this part, it is advisable that you have the glass panels cleanly cut to their respective sizes at your local supplier’s shop.
Step 2 – Attach Front and Bottom Panels
Put the bottom panel on a working stand. Make sure your stand has smooth, clean and even surface. A good tip is to place a block of wood on top and in the center of this bottom panel to press it to the stand and help prevent it from moving while you work.
Attach the front and bottom glass panels at their edges. The bottom panel lies flat while the front panel stands on its edge. Bring the two panels together, make sure that the edges of the front and bottom glass form a 90-degree, right angle. Glue the edges using aquarium-safe silicon adhesive. Apply the glue on the inner side of the edges or angle.
Step 3 – Fasten the Front Panel in Place
To keep the front panel upright and in place while the adhesive dries, you can support it by using duct tape as harness. Simply stick one end of the tape to the inner side of the glass, while the other end is attached to the block of wood on the bottom glass panel.
Step 4 – Steady the Newly Joined Edges
The adhesive will not dry immediately. Along with making sure that the front glass stands up straight and at 90-degree angle with the bottom plate, you must also make sure that the joint edges are steady and tightly attached. For this, you can use duct tape to secure the edges.
Step 5 – Allow Adhesive to Dry
Allow the adhesive to dry for 24 hours. The front and bottom panel abutment will be your reference point for the rest of this project, it is important that this joint is secured and fixed tightly.
Step 6 – Attach Back Panel
You can now attach the back panel. Simply glue the edges of the back panel to the bottom panel as you did with the front side. Again, use duct tape to act as harness between the inner side of the glass and the block of wood on the center of the bottom panel to keep it upright and straight.
Step 7 – Attach the Sides
When the back panel is secured, you can begin attaching the sides of the aquarium tank. Simply glue the edges of the side panels to the edges of the bottom panel and along the edges of the front and back panels.
Step 8 – Allow Adhesive to Dry
After all the edges have been glued together, you need to wait for another 24 hours to let the adhesive dry thoroughly.
Step 9 – Seal the Edges
The next day, remove all the attached duct tape and the block of wood from the bottom panel. Turn the assembled aquarium tank upside down and apply sealing adhesive to the outer edges of the tank. Put the rubber trims in place and then dry for at least 5 hours.
Step 10 – Test the Aquarium Tank
When all the sealant has dried, put the tank on its upright position. Add water. If there are leaks, empty the tank and repair the leaks with glue or sealant as needed. You can wait up to 12 hours to get a good observation of your tank to make sure it doesn't leak. If everything looks good, you can add the decorations and accessories and start filling it with fresh water for your fish.
