I came across this video while searching "repair chip in aquarium? on Google, and found it interesting and worth a try. My 55 gallon tank has about a 1" chip in the glass that goes almost to the sealant, I managed to pry the chip out of the glass, and cleaned up the area and I'm going to try to repair it with the
CR Laurence Low Vicosity UV701T and see if it works.
My SunSun 402B canister filter has a built in uv light that I'll use to cure it, and will update everyone in the next 2 weeks because it's vacation time right now!!!
That's what I'm wondering too, so I figure I'll give it a shot and see how it works. I figure the worst that can happen is it fails, and I have to replace my 55 gallon tank. I plan on trying it out to see if it'll hold up, but my plan is to let it cure for a week and then fill the tank out on the balcony so if it doesn't hold up it won't flood my apartment. However if it works then it'll be a new way for fixing tanks...
