Water getting Behind the AIO Piece in custom 60g cube

[addicted_to_reefing]

How’s it going! I started cleaning my new to me AIO 60 gal tank and once I filled it up I noticed that there was water behind the AIO piece in the back of the tank. The water level does not drop or anything, I can just see water behind it. Is this going to be an issue or should I remove it and re attach it with aquarium sealer. Thanks in advance!!

What brand of tank? Are you referring to the back chambers?

Not sure of the brand but yes, where the chamber piece has been attached to the wall I could see water around the top edge where the silicone was used to hold it on. I’ll take some better photos when I get home. The water doesn’t leak from the tank at all. Just see it between the AIO part and glass.
