Deep blue rimless 75 seal turning orange

[leebauer]

Discovered the bottom left seal of my rimless 75 turning orange where the sand bed usually covers it up , concerned with tank failure I snapped a pic and sent an email to deep blue, rather quickly they sent a two sentence reply stating "it looks to be staining and they do not see any damage that would result in a failure". To me I'm not really satisfied with the response as I only dose coral supplements (caribsea A and B) . And when should I be concerned with the failure? When it's dumping water on my floor? I am wondering if anyone else has seen black silicone do this and should i be concerned enough to take the tank down? I emailed deep blue back with my concerns,

and have yet to get a response.

I have a deep blue 75RR. My silicon turned orange like color also after like 2 months. I didn't sweat it and I have had it running for over a year and has been perfectly fine with 0 leaks.
