I just got this baby up and running for a couple weeks now and tonight I was cleaning the the glass and noticed a weird U shaped crack in the tank. You can only feel it on the outside of the pane and it’s not leaking any water. Is this my fault or manufacture defect? Do you think seapora will cover their warranty if I didn’t fill out their warranty card and it’s 3 days past one month of warranty. Lol picture of my new indo gold included
