Nice to see I'm not the only one listening to Outkast once in awhile lol
Generally, what I like to see on LPS are gentle, long pulses of flow, though some can also live happily under a more chaotic flow.
Personally I'm SPS dominated, so the "left over" from the strong flow I have on the upper end of the tank which is tailored for acros, is enough to produce a nice flow for the LPS on the bottom.
If you notice, on your video some corals are moving a bit chaotically, while others barely move - I would try to distribute it better with a less narrow flow and spread it more along the width of the tank.
You can also try to create a gyre affect, which creates waves from side to side and produce a nice even movement - that's one of the easiest ways to implement a good flow without over thinking it.
