What kind of caulking do I use to?

What kind of caulking do I use to put a divider in a 55 gallon tank? It is going to be half a sump and half a resivor. Thanks

100% silicone. Just make sure it does not have a mildew inhibitor such as the type used for bathroom applications. Check your LFS or Dow Corning.

Yup phixer is right. I know ge is a popular brand & what I use & the door & window type doesn't have mildew resitant in it unlike the bathroom kind as phixer mentioned. Also with the ge brand Silicone 1 doesn't contain the mildew resitant, but silcone 2 does.
