I have a 90gal drilled All Glass tank I bought new 5.5 yrs ago. It is on a very level/sturdy home made stand in my basement and is a beautiful reef tank. Apx 4-5 mths ago I noticed a hairline crack or scratch on the front side in the top right quardrant not strating from an end. It started out about 7-8 inches and is now about 12-13 inch long. If I move my vantage point closer, higher/lower etc the line seems to vanish or I can see more or less of it. So...is this a crack I should be worried about or a scratch that gets longer when I wipe my magnet cleaner across to clean the glass? It is very straight and almost parallel with the ground and is about 6 inches from the top. I can slightly feel it with my finger nail but only in some spots.
I need help to determine what exactely this is and what I should do?
I am worried if it is a crack, it could blow out and be a disaster.
Attached is a picture in photo bucket but is a little deceiving because you can only see part of it.
Thanks in advance for any and all advice.
