Your video shows a cleaner wrasse, several lyretails, a chromis, 2 clowns and a flame hawk. What happened? I've always been tempted to add a fu manchu or a fuzzy, but want to keep small fish - and I've heard the fu mancu's are hard to keep.
Meant to comment on your ICP. That 1589ppb Phosphate seems really high, but if your corals are good like in the video, and you don't have a huge algae problem, I wouldn't worry - except maybe you got ripped off from your ICP test. Phosphate chemistry is really complex, so maybe you do have a lot that is somehow not biologically available.
I don't think ICP has any value for Nitrate, Phosphate, Alk, Salinity or Nitrate. I pay for an ICP about once per year to see if I have any metals that I don't otherwise test for, and it is also useful for seeing how far off my Ca test is.
Nitrate and Phosphate are too high when algae or cyano is a problem, or coral is doing badly. I do test Nitrate if everything else is fine, but only to check if it is too low and am experimenting with dosing it. I do test Phosphate but only to decide when to change my GFO.
Alk doesn't matter at all what the absolute value is, only that its consistent. So any hobbyist test works fine even if it isn't that accurate.
I highly recommend a High Precision Hydrometer from Tropic Marin for salinity. Even if you use something else to monitor it, it is a good check if that something else is accurate. Your salinity appears very low from the ICP test - you do have Sodium and Chloride reported.
