New tank leak from brace?

[Keithb22]

Hey everyone, just doing basic maintenance on one of the tanks and noticed a leak. It’s been there a while and I thought it was from water changes. I felt the inside of the brace and it seems there is a section of about 1/4” that has no silicone. The other side is sealed and I can palpate it. This is the only spot that’s doing it and the actual vertical seems loom to be well sealed. There are parts that are abnormal and I circled those but it looks to be where the glass is mated to the glass and again the seam looks fine. Any thoughts on if this is normal or alright? Thank you for any help.

When I had my framed 180 I would get a lot of salt creep for the back trim. I don't think the frames are actually silicone to seal all the way but more to hold the trim in place and salt creep seems to find any way it can to form. I would just wipe it off once in a while. The blemishes in the silicone don't look like a failure stating but more like a blemish to me. The silicone failures I've seen start at the inside edge and then into the seem. The entire inside edge on your tank looks to be intact. JMO but I'm far from an expert.
This is what mine seam failure looks like. I had a full separation in an upper corner so I broke the tank down before is let loose.

The seams at the top of the tank are not always 'waterproof' - if your water level is too high (or in your case - water is splashing too high at that area - you can get drips. I would not consider it a structural issue - if you can dry the area and seal it IMHO you should be good to go. (maybe adjust the flow of your powerhead - and verify that there is no crack in the glass itself). Of course if there is any damage to the glass or cracking in the brace - thats a different story

Correct - I had the same thing

Both you thank you so very much. It’s a cichlid tank and I’ve got 3 different filters and a bunch of surface agitation so likely from what you guys mentioned. The glass and other structural pieces look great. Such a relief, I’ve read so many RS posts that I’ve become paranoid. Again appreciate the expertise.
