MP40 break seals of tank?

Only if the tank was a cheapo or had a defect.

Are you planning to create a wave? Creating a wave does place additional stress on a tank but most tanks should be fine.

No it won't. You will probably find reef crest is better then wave mode. It bounces the pump between low and your set point randomly. It makes for some incredible flow variations and coral movement without the fish jerking back and forth all day.
