New reefer here, 2.5ish month old tank, i’m currently on holiday and it grew fairly quickly in around 1-3 days so this camera is all of the footage that I have of it, but can anyone help me id the long flowy (algae?) thing, it doesn’t really look like any of the usual ones I see but i am inexperienced, it breaks off at around 2:42 too, but a new part has since come/grown into view a day later. Thanks.

I’m not a expert by any means but it kind of looks like Dino’s to me, I had some of that brown long stringy algae and dosed my nitrates up (they were bottomed out) and it all went away! Make check your nitrate and phos when you get home and see if
