Update. Started with 1L flask, added ~100mL phycopure copepod blend out of fridge (let it warm first), to look light brown cloudy. After one week...


Not bad.
Under microscope it's unexpectedly still a blend of t-iso and chaetoceros. I'd estimate t-iso outnumbers the diatom cells 3 or 4 to 1.
And I think the original was closer to even split.
Good to have options.
