I noticed that the seals inside the front corners of my 120 seem to be splitting. There are small, thin, vertical lines in them where it looks like it has stretched apart. So far, there are no signs of a leak (no salt creep, etc on the outside). The tank has been setup for almost two years and is level. Has anyone seen this happen? Any suggestions? TIA.

Hmm, do the edges of the seal "flap"? as in you can lift up the edges with your finger or some thin object--easily? If it doesn't, don't force it up.
