I apologize ahead of time for the quality, happened very fast, and did not have time for a proper setup.
Captured this short video of a couple of zoospores being released from sporangium at 0:38secs link below.

Not quite sure what's going-on in the image, but I like the image very much!

when moments like these come along, grab what you can to capture them.

well done.

the image happened to capture the Tupperware lid acting as the blue filter below the condenser with Köhler illumination, hence the letters "A Microwave" written.
The real treat is the video that shows a zoospore activating its cilia for the first time.

What a very interesting video. I never saw this before.

A great catch! Really nice work. Have you identified the filamentous algae?

What a very interesting video. I never saw this before.

I was able to find one similar video with a different method, where multiple zoospores are shot out like a cannon but never the whole content being one giant zoospore. After some time they develop a foot and take hold onto whatever they can

I have not unfortunately, I can tell you that it seemed like a synchronized event happening within a 10 min span right before sunrise, I'm going to see if I can obtain more footage this AM.
