Joining aquarium glass primarily involves using a specialized aquarium silicone sealant to create a watertight bond between panels. This method is reliable and widely used for constructing or repairing glass aquariums.
Using Aquarium Silicone Sealant
The process requires careful application of aquarium-specific silicone. Regular silicone or sealants are not suitable as they may contain additives that are toxic to fish and other aquatic life, or they may not provide a sufficiently strong or durable bond for holding back large volumes of water.
Preparing the Glass
Before applying any sealant, ensure the glass edges are perfectly clean, dry, and free from any dust, grease, or old silicone residue. Cleaning with acetone or rubbing alcohol can help prepare the surface for optimal adhesion.
Applying the Silicone (The Key Step)
Based on standard practices, the application of silicone is a critical phase for successful joining. Here's how it's typically done, incorporating the details provided:
- Prepare the Sealant Gun: Place the aquarium silicone sealant in to the application gun.
- Ready the Nozzle: Make a small nick on the nozzle of the tube with a sharp tool. This controls the bead size.
- Apply the Bead: Apply the silicone slowly and observantly to three edges of the glass also evenly holding silicone at the angle of 45 degrees. This angle helps ensure the silicone fills the joint effectively.
- Prepare for Joining: Be ready to join the pieces immediately after application.
Joining the Pieces
Once the silicone is applied to the edge(s) of the panel(s) being joined:
- Join it with the glass to be adhered without too much delayed. Align the edges carefully as soon as the silicone is laid down.
- Press the panels together firmly to ensure good contact and spread of the silicone within the joint. Clamps or tape can be used to hold the panels in place while the silicone cures.
- Smooth the internal bead of silicone gently with a finger or tool dipped in soapy water if desired, creating a clean, watertight seal on the inside. Avoid removing too much silicone from the joint itself.
Curing the Silicone
After joining, the aquarium must be allowed to cure completely. The curing time can vary depending on the silicone product, humidity, and temperature, but it typically takes at least 24 to 48 hours, sometimes longer for thicker beads or larger aquariums. Do not fill the aquarium with water until the silicone is fully cured.
Tips for Success
- Always work in a well-ventilated area.
- Use masking tape along the glass edges to create clean lines before applying silicone. Remove the tape immediately after joining and smoothing.
- Practice applying a consistent bead of silicone on scrap material first.
- Avoid bubbles in the silicone bead.
- Ensure the glass is cut precisely with clean, straight edges.
Using the correct technique and dedicated aquarium silicone is essential for creating a durable, watertight, and safe environment for aquatic inhabitants.
