Yellow discoloration on Silicon

[drtash]

I recently purchased a brand new 220 gal tank. Within about 3 days the silicon became stained yellow. All the tubing I purchased from the company turned yellow too. The tubing I purchased from Home Depot is clear. The tubing looks like a "strep culture" growing on it.
Suggestions of what it is?

Was this a custom made tank or a major manufacturer (Oceanic or similar)?

This tank was bought from a company in pearl river ny. Big company.

not custom made

That is really strange!! I know that the silicone on my SCUBA mask turns yellow and there is nothing I can do to stop that...but the silicone used on a tank should not do that. What big company is in Pearl River?? I live close to there and my gf works there.

I use a 25 gallon hex tank as a mixing tank, the silicon seams turn yellow on that but not in my display tank. I use reef crystal and I blame that.

I use reef crystals and have a 20g mixing tank and the silicone is still clear.
I would be more inclined to think its the type of silicone used rather than a salt mix.

This happened to the sump on my one tanks. I use the same model as a sump on another tank and there is no staining. I use instant ocean. Glad it's just in the sump as it is quite unattractive.

Beitels in pearl river. I asked him and he did not have a good answer for me.
