Intro: Reseal a Glass Tank Aquarium
If your tank has to be resealed you may be intimidated to tackle it. Depending on the size of your tank replacing it with a new one can be very costly. If you need the tank ready in a day, resealing isn't an option. Make sure you give yourself time for it to dry so it can be done properly.
WHAT YOU WILL NEED
- Nice stable work space ( I used a space that I could let the tank sit for a few days,was at a comfortable height to work with and has decent ventilation for the fumes).
- Utility knife and a razor scraper
- rubbing alcohol and cloth
- disposable gloves
- tube of aquarium sealant ( do not purchase any with fungicide or any additive that can harm the tanks inhabitants).
- needle nose pliers
Step 1: Supplies
Here is a picture of the razors I used. I found myself using the scraper more than the other.
Step 2: Removing Old Sealant
I took my razor scraper and slid it underneath the old sealant and moved it down each corner of the tank.
Step 3: Onto the Other Side of the Seal
I went to the other side of the seal and did the same thing
Step 4: Pliers
Pliers came in handy to get into the corner pieces and remove what I couldn't with my hands
Step 5: Clean the Corners
I used rubbing alcohol and gauze to clean the area that I was going to apply the sealant to.
Step 6: Vacuum
This is important if you're resealing the bottom, make sure you get up all of the old sealant and dirt.
Step 7: Tape Up the Area
I used masking tape, but you can use painters tape as well. Give yourself a little space on either side of the joints so the sealant is not just in the corners of the tank.
Step 8: Add the Sealant
Apply the sealant to all the areas. On the sides of the tank I started from the bottom and brought the sealant up.
Step 9: Spread the Sealant
When you applied the sealant take your finger and run it down the freshly applied sealant so it flattens the bead you just put down. Remove the tape! Don't let it dry because your tape will be hard to remove.
Step 10: Let It Dry
For at least 24 hours.
Step 11: Test the Tank
I added a half tank at first, kept an eye on it for 24 hours, filled it up the rest of the way and tested another 24.
