how long should tank sealant dry before?

  • We are currently upgrading MFK. thanks! -neo
If it is just the aquarium safe silicone..I let mine dry for at least 48 hours, before adding any water.
 
i agree with jd the instructions on my sealant stated it would set up in 24 hours but needed 48 hours to totally cure.
 
instructions on the stuff i use says 48 hrs
 
imo...

24-48 per tube, when re-attaching my glass to rubber i have waited 6 days.
 
If you can smell it, its probally not cured yet. At least thats what I go by.
