I was told, that if you are designing a tank for a certain size.....you get a certain grade/thickness of material. Now...if you are adding a wavebox, that needs to be increased. As to how true that actually is, I can not say.
The other issue, and this is way more important is in connection with wave height and overflows. Its possible to get a decnet sized wave on a tank, and that can cause splashing and or spills at the ends. The up and down motion can lead to a rush of water into an overflow and then a lack of flow into the overflow. If you have just a singe overflow it can cause the overflow to be a little less efficient and and can lead to an imbalance between pumped water and and overflow water out.
I really like the idea of the great water flow that can be created with these units....and for very low wattage.
