No negative affects from what I've noticed on corals or structural integrity of the tank, just an eye sore

Sunlight might have done it but my sump is closed off the the light all day long and it seems to have got it worse then the rest of the tank so I'm not to sure what is causing it…

I have a feeling its the silicone or the light over the silicone, if its aquarium safe then there is not much to worry about although it will most likely drive you insane as that tank is a masterpiece.
Hope you get it all sorted out.

Your dead right about it driving me insane! haha so i think what I'm going to do is cut the entire tank and sump apart and clean it all up then get my hands on a few tubes of the clear aquarium silicone and get rid of those pesky seams haha and then i know for sure 100% that there is nothing going to be effecting this tank, and with all the extra stuff I'm doing and adding to it not having to worry about the silicone will just be one less thing i have to worry about
