Bubbles in my silicone- should I be worried?
During my weekly water change, I noticed that all four corner seals are riddled with bubbles. Most are small, but some are over half a centimeter. I don't know how long they've been there- I just noticed them today, but I bought the tank off Craigslist about 18 months ago, so there's no telling how old the tank is. Should I be worried? Am I going to come home from work some day soon to find 30 gallons of water soaking my landlord's carpet?
