Does this need to be re-sealed?

Would you tear this tank apart and re-seal between the glass panes? I'd rather do it now before the tank is setup than face an issue a few years down the road. Any input is appreciated.

That doesn’t look terrible, but how deep is the tank and what depth is that blemish at?

Tank is 30" deep. These are the front glass faces, top picture is left and bottom is the right side. Both are in the upper half (1"-12" from the top). The tank itself is 84"L x 24"W x 30"D.

Deep tank is a much bigger concern, but the glass is probably thicker than I perceived by looking at the photo.

I would take the tank outside, put it on a flat, leveled surface and then take another picture(s) of the blemishes. Fill the tank and take similar pictures and compare them to see if there is any differences between the two, like the expansion of gaps.

If there is movement inside the seam then I would be inclined to reseal, otherwise it is still just a blemish, and lots of people live with these things without issues.
