Why does tank silicone look orange?

[Krixic]

Got a new tank used and just now noticed that the edges of what I'm assuming is silicone is orange. Not all is this color. Some areas are black (the normal color) others a orange. Pic attached. Is this bad? I don't really mind it all too much as long as its not structurally unsafe. I don't remember the edges being this color as I tend to be very particular about buying used items and check everything. But perhaps this slipped my head?

If it's the same phenomenon as the on described here (and the neon yellow I've experienced with silicone), you might want to check out this recent thread and contact the OP to follow up. In my case, I never got to the bottom of it and it didn't affect my reef, but mine was closer to the color in the pictures listed below:

Silicone yellowed

So I picked up a used 150 gal for an unbelievable price ($350 with stand and all plumbing), but the silicone sealant has yellowed. The tank was sitting dry, so I'm not sure if this is why or if it's due to some other reason. It looks like perhaps it was a DIY job. I'm leak testing it now, and...

Strange, well I probably wont worry to much about it. If anything I might just razer away some of the yellow and do a reaplication on silicone. Although, should I give bleach a shot?

I have no idea :/ I never bleached mine and ran it for 5 years without any issue (color never faded), but clearly the bleach was effective for the other person dealing with it. If you have the time, bleach won't hurt the tank, so you could always test it and report back

Sounds good to me. Might I ask though, how do I safely remove bleach from the tank without leaving any residue? Never used bleach in the tank before as it always seemed tabou.

You can either air dry and it will be gone or use a dechlorinator like prime. Rinsing (dilution) will also work, but is pretty labor intensive.

Alright, well here goes nothing. Ill update if any changes occur over 24 hours.
