I would have to think it would have an effect on the life of an aquarium. How much? I don't know. I just tried to do a search to find a failure do to vortechs and didn't turn up much. I'm just sitting here thinking about when a wave hits you at the beach. Or the fact a tsunami is just a small wave before it hits the shore. On the other hand though, I think most of the quality aquarium manufacturers build pretty robust tanks that can take the beating. Only time will tell though.
