reef mat sealant

[Herbie's Reef]

I just cut all the baffles out of my waterbox tank in the process of installing a reefmat 500. The plumbing the reefmat will be connected to is underwater, I will need to use the sealant to connect the corrugated hose to the included connector. How long must I wait after using the sealant before it is submerged in my tank? Could I place it in right away?

The corrugated hose will be sealed onto a connector which will be connected to my main drain underwater. So the sealant will be submerged entirely.

edit: the manual says it can be used right away but the manual also doesn't seem to think it will be fully submerged

I'd wait 24 hours for any sealant, personally.
