I might be able to post a shitty phone video tonight or tommorow if desired. Dont think it will show much. It's just a holding tank for some rock and a bunch of detritus.
My verdict would be you could run it 10% in constant especially in a more sps and high flow tank, and the H1 wave for most other things and get 100% of your flow from it.
So basically going to be more ideal if you either believe in running at low % for enhanced longevity, or might have use for also mixing lots of salt or a bigger tank later. (IE for me w/ a 300g I bought them to supplement and didn't need, if I started a 40b, I'd probably use one since it's on hand rather than trying to get smaller, but if buying new for it, then I'd get next smaller.)
