So I am new to all this. I am still learning about the art of aquascaping and fish keeping. I inherited a 75G tank from a friend of my wife. After reading the thread KingD started about his 75G rehab I realized I need to take a closer look at what I was going to do with the new tank I have acquired. The tank is quite scratched but none are too deep. I believe I can buff them out. But I had never considered resealing the tank and on close inspection, the silicone in the corners of this tank is in terrible shape. There is next to none on the inside of the tank and the silicone in the seal is very brown and decayed looking. It makes me wonder how the thing even held water. So given all this I am left wondering, should I break this tank down into plate pieces and rebuild from the ground up? Would anyone else do that? Part of me wants to do just to see if i can since I have never done anything like it before. I bought a couple of different sized scraping tools and I am going to remove the top and bottom braces and start scraping this thing down. I will probably try and take it all to the way to plate pieces which would make buffing out the scratches easier. To reassemble, would I simply use silicone to bind all the pieces together and then reseal the inside joints? Should I do it all at once or should I let the bond cure before doing the inside? 1 week on the cure time? Any special way to reattach the braces or just silicone them in place? Any advise is appreciated. I will see if I can attach some pictures later this afternoon. Thanks all.
