I have a brand new aquarium I purchased for my return to the hobby. It is 74 gallons and going in my office. I was playing with dry aquascaping layouts and somehow scratched my glass. I even took the precaution of placing 3/8" inch thick foam board on the bottom of the aquarium to protect it from the dragonstone I was using for initial layout ideas. Well somehow I now have what looks to be a scratch. I am wanting to double check that this is not a crack forming because a piece of stone landed too hard or something. It is about 3 inches long. I can barely catch my fingernail in the scratch. I pressed on area with my thumb, and no growth or travel of scratch. I slid the aquarium off the stand to check the underside, nothing, it's "smooth as glass". I am assuming i have a scratch and not a crack, BUT this is a whole lot of water and it is the bottom panel. I figure I would run it by some others in the hobby just to double check. I was thinking of filling it with UV resin like for car windshields to bond and strengthen it. I think I will do a partial water fill to see if it leaks or grows. Thoughts? Thanks for the feedback.
