did you relevel it with water in the tank or drain it?I have had my reefer setup for a year now. Seeing them facebook post really have be paranoid and I'm constantly checking seams. I really think having the tank and stand level is the key for longevity. When I set my tank up it made sure it was 100 percent level. After several months I noticed it was slightly off so i had to relevel the tank. With that being said it was in a brand new house so it took a little for the house to settle. I would recommend checking to make sure the tank is level every few months or so.
