It isn't that difficult to replace a panel of glass on an aquarium the size of yours.
The first step is to remove the old panel. This is best accomplished running a razor blade along the silicone sealant seams that join the panel you want to replace to the rest of the aquarium. Don't give in to the temptation to pull on the glass pane....keep using the razor blade until the old glass separates easily.
Once the glass is free, remove any traces of silicone sealant from the glass still on the aquarium by scraping carefully with the razor blade. Then clean any remaining residue with acetone. Removing all of the old sealant is
very important or you might not get a complete seal when you put on the new glass.
Allow the acetone to dry completely and then run a thin but solid line of silicone aquarium sealant (available at most pet stores) along all of the areas where the new glass will join the old glass. Put the new glass panel in place, bottom edge first and at a slight angle, Once the new panel is aligned correctly then press it firmly but carefully (glass breaks easily under pressure) against the aquarium. Hold it in place with duct tape.
Apply a second solid line of silicone sealant along the inside glass joints and then run your thumb along the sealant to smooth it and force it into the glass joint. Once this is done then allow the sealant to cure for 24 - 48 hours. Don't get impatient or you'll have to start all over again.
Refill the tank with water and allow it to stand for a day or two. This job is best done someplace that will be easy to clean up if you have any leaks.
After a successful test period, drain the tank and it is now ready to be moved to its permanent location and set up.
Common mistakes to avoid:
- Make sure the glass you're using is the same thickness as the glass you're replacing. Unless you're comfortable cutting your own glass then it is best to have a professional glazier cut it for you. Make sure the new piece is of the same dimensions as the old piece and that the sides are straight.
- Make sure you're using 100% non-toxic silicone sealant that is designed for aquarium use.
- Make sure the glass is completely clean before trying to join the new panel to the old ones.
- Make sure you use enough silicone sealant.
- Make sure the new glass panel is correctly aligned with the rest of the aquarium.
- Make sure you allow adequate curing/setting time for the new sealant. High humidity will slow down the curing process.
- Duct tape won't stick well to glass under conditions of high humidity so try to do your repairs when the weather is cooperative.
Hope this helps...
