Dinos with Bryopsis? Help!

[Snot Otter]

My tank is about four months old. I made several posts last week regarding my concerns with algae. I finally purchased a microscope, and based on what I am now seeing, it certainly looks like dinos and something else. Under the microscope, however, nothing appears to be moving. I've been dosing phytoplankton daily. Some kind of green algae (perhaps Bryopsis) is starting to take over the rocks, and the sand has brown spots.

Any help would be appreciated.

Parameters:
Temperature - 79 degrees
Salinity - 1.024
pH - 8.0
Ammonia - 0
Nitrite - 0
Nitrate - fluctuating between 0.7 and 1.7 ppm, but it did bottom out at 0 for a couple of days several weeks ago
Phosphate - fluctuating between 0.03 and 0.05 ppm
RODI TDS - 0

I apologize for cross-posting. I'm still new to forum and trying to learn the rules. I can delete this thread if that would help. Thanks.
