Drained tank to clean and leave empty since going away for 3-4 weeks. Plan on leaving empty so no worries about audden leak from hose or FX5. While cleaning the tank I noticed along the bottom sealant there look like air bubbles have formed in many places. Is this common and I just not use to seeing the tank empty or am i in for a leaking tank soon?
Please help soonest. Cant upload pics yet but will try to get them here.
