    Yes it is best to seal around the hole. If the top base cracks then the water will not run out the hole and along the thread of the tank connector.

    Yes the coast to coast acts as a brace. Don't make it to shallow as the holes will be very close to the top and the weakness will be there. Allow at least 80 to 100mm
