What's up guys. So this has always been in the back of my mind... I got a 210 Aqueon megaflow tank from a friend of mine (I've seen it setup with water and fish in it at his house.) He said he had it for around 5 years and he bought it used. He thinks it was around 4 years old when he got it. I've had it setup for a year now and no problems. So it's around 10 years old. There is no sticker on the bottom of the tank- its ripped off so I don't know exactly how old it is. Do you think I should start thinking about replacing it soon due to age? The seams seem fine. There are no bubbles in between the panels. The silicone in the tank is still there but on some spots you can lift part of it up with your finger. Should I think about replacing the tank soon? What do you think?
