resealing a tank

[robj6767]

Hi there, I just got my hands on a 75 gallon tank that was in rough shape with the seals. As i have never done this before with a tank, I'm looking for any help on tricks or information on how to do so. My main question is, do I have to seperate the glass and do the complete seal or can I strip off the old inside and then just reseal fromt he inside. The seal across the bottom of the tank seems fine and it is only the edges on the sides that are a bit old. The tank came from an aquarium and was already predrilled on the bottom, but the previous owner sealed that with a plate of glass. I don't have any worries about that leaking as its got a very good seal around it. What I do have a worry about is only resealing the sides. should I just reseal the entire tank or will the silicone adhear to the silicone across the bottom? If so, is a company called xiameter a good place for buying silicones online? I've heard good things about them but just wanted to double check.

The best way to go about this is to first strip off the old layer silicone, But do it one corner at a time, and take a few pieces of tape (Preferably not duct tape, but the clear packing tape, As duct tape will leave a residue which you will have to scrape off) and tape the aquarium into its shape. This should hold its shape while you do your work. I would only recommend doing one corner at a time, and the bottom edges to be done after the corners are done. After all the corners and edges are done (24 hrs each for drying) you can peel off the tape and you have a resealed tank. Also to take off the old layer use a sharp razorblades. Don't worry it will not scratch the glass unless you try to use the corner lol. And finaly for the silicone i would use a GE II brand which you can get at a home depot or lowes, Anything else will work, just make sure it is 100% silicone and does not have any latex's or other ingredients. Hope this helps
