A leaky aquarium tank can be a big problem. Many leaks begin with minimal water leakage, but if the problem is not solved it can lead to the entire aquarium breaking or wasting a lot of water.
Steps
Step 1. Identify the location of the leak
- If it's not noticeable, look for where the tank is wet.
- Look for metal corners that appear to have separated from the glass, and places where the sealing material protrudes in the corners.
- Run your fingers along the edges and if you feel water, move them up until the surface is dry again.
- Mark the location of the leak, or where you suspect it is, with a marker.
Step 2. Remove enough water to have room to clean and dry the area around the leak
If this is very low in the tank, you may need to move the fish and aquatic plants to a temporary container or other aquarium as you proceed with the repairs. Remember that the sealant you use to repair the aquarium must have dried before refilling the tank, so make sure you keep your fish and plants healthy.
Step 3. Remove the old sealant around the compromised area with a scraper
If you are sealing the tub from the inside, be careful not to let the sealant drip to the bottom.
Step 4. Wipe the area with a clean cloth dipped in acetone to remove any residue and other external material
Dry with kitchen paper and wait for the air to dry for about 15 minutes.
Step 5. Apply 100% non-toxic silicone to the leak area
Let it dry and dry for at least 12 hours, but better 24.
Step 6. Refill the vat and inspect the leak
If you have removed the fish and plants, reposition them when you are sure the leak has been repaired.
Advice
- You could try to fix the leak from the outside of the tub, but usually the repair is most effective if done inside, as the water pressure will strengthen the gasket by pushing the silicone out, against the glass, while pushing it. away from the glass when applied from the outside.
- Very large aquariums have more water, therefore more pressure on the seals, and can be very difficult to repair.
- Ask a professional aquarium material supplier what products are recommended for repairs. Make sure that if you use silicone, it is labeled "non-toxic" and "100% silicone". Also make sure that the silicone sealant does not contain fungicide and is a very elastic product. Also choose the suitable color, usually between clear, white or black.
- You could use a heat lamp or other portable heat source to let the sealant dry first, but do not heat above 43 ° C.
- Don't get rushed!
Warnings
- Do not try to move the aquarium when it is full of water, the movement could distort the seals and cause the aquarium to leak or break.
- Never use solvent-based glues on aquariums.
