You should use acid cure silicon not neutral cute. It the same stuff the tanks are made fron, just make sure the tube say for aquarium use, selleys make a good one.

I assume you are just using the silicon to seal the gaskets on your bulkheads?? all your other plumping will ideally be pressure pipe and should be glued using the correct pressure pipe glue, which actually melts the plastic togeather, silicon wont hold joints in pressure pipe for very long.

As for how long to leave it, if you can you should wait 24 hours or so, but I have drilled installed/glued bulkheads and refilled with water in less than a hour, I have also used silicon in my tank while it was full of water to glue over flows etc with no problems. The acid in the silicon is I believe bascially vinigar (could be wrong here) its safe for fish and will cure under water.

.

& as you use acid cure silicone, you cant use laminated glass as the acid cure eats away the laminating silicon.
