The seals on my 180 gallon seem to be developing air bubbles. The tank is around 3-4 years old and I don't remember the bubbles ever being that noticeable. It appears to have got a bit worse over the last year. Is this something to be concerned about? I don't mind how it looks but is it going to cause my seals to fail? Both the left and right side seals up front look like this.
