i often clean the inside and outside of my tanks with a razorblade and last night i screwed up big time. i wasnt being careful and accidentally made a few small incisions in the silicone lining. oops. water was slowly leaking from the cuts, so i quickly got some silicone and put a few big gobs in the leak. it is OK now but last night i was freaking out. Now i got some big ugly gobs of silicone on my tank. at least it was only a 30 gallon and not my 90.
