I picked up this 60 cube for mad cheap. I can see on one seal where it is cloudy along a good portion of it and the tank was manufactured in 2014 so to be safe I am planning on tearing it down and completely resealing it. Because it is rimless I have decided to use the Momentive RTV108 silicone. My only question is how much am I going to need to do the entire tank? The tubes aren't cheap and I don't want more sitting around than I need, but also want to have enough when assembly time comes.
