48 hours of water-tight testing, and I'm passing worth flying colors. I gotta say, it feels so good to have not royally screwed this up (so far). I let the silicone cure for 92 hours before filling.
I was a little nervous about doing it in the garage because it's pretty cold, but I wasn't willing to risk the carpet inside in case I failed and it leaked.
Here are pics... Notice the chunks of glass at the edge (picture with my finger). I didn't see these when I bought the tank. They must have happened during the transport. I don't think it's causing anything more than an eye sore. There are no cracks. Thoughts?
