Newly built tank, silicone concern?

[Mount_Prion]

If my tank was newly built, like within the last 2 weeks, should I wait a while to fill the tank with water?

Somebody at my LFS said he would wait another week or two. He said even though they say the silicone takes 2-3 days to set, he's seen new silicone split when a tank is filled if it hasn't totally cured.

Frankly I was a little skeptical, and obviously I want to be able to build my tank sooner rather than later.

Thoughts? Is this baloney?

I know when I purchased a glasscages aquarium years ago they had a date in magic marker written on it. Stating when it could be filled. I think it was 4-6 weeks after build date

I have replaced glass, and repaired tanks with silicone, and filled them the next day.

It depends on the silicone used
Ge1 takes 24 hours and you are good on tanks under 70g in my opinion.
Scs1200 takes 2-4 weeks to cure properly on any size

I would say if your tank is two weeks old, you're good
Most silicone cures in 48 to 72 hours. And even a slow cure silicone would be cured in two weeks
