The reason to use waves is clear, a 1" wave on a 180 is 3.74 gallons of water, with a wave about every second that is 13464 gph of flow and done with next to no energy use and heat input. On the other hand, that also means roughly 25 pounds of shifting weight, so yes, it does stress the seams. I personally do use a wave, but 1/2", you can dial down the amplitude. In no case would I recommend making a wave on anything but a top end aquarium you bought new, you will want overkill in the glass and the stand needs to be rock solid and level. If a tank was constructed in accordance with Timoshenko's formula, no corners were cut in material and it is structurally sound, it should last approx 20-25 years, if you make a modest wave, you shaved off 10-15% of the tanks life. FWIW, you reduce the life at least that much by simply draining it and moving it and after 10-15 years, most tanks are done, scratched, damaged and due for replacement so if you start with a quality aquarium and stand, I don't believe this is a real concern. Nature does not do random, there are reliable and predictable tides and waves and storms, which are also more or less seasonal and predictable. The wave lifts and suspends, the tides carry it away, the storms periodicaly destroy and purge.
