Brackish 20 Long Chesapeake Bay Aquarium

The 20g long cyano problem has been reduced to a minimal amount by cutting back the lighted period to 3 hours per day, darkness the rest (not total blackout though). The tank looks a lot better. I went collecting on Saturday, and we caught everything except for pipefish and blennies. The water temperature on the Bay was 49 degrees, so those species probably already headed out to deep water. I added a couple colonies of tunicates to the tank along with another attempt at growing Ulva. I also tossed the old red macro algae for some healthier specimens. The old was holding it's own, but the new brought a few amphipods to the tank. I added a couple live razor clams to the 20g high along with some tunicates.
Regarding the tunicates, razor clams, and mussels (a.k.a. sea squirts or sea grapes), I'm hoping that they'll help with the detritus, but I may have to purchase some food for filter feeders to keep the alive long term. Again, this is an experiment. What works well will continue into practice and what doesn't will be a lessoned learned idea left in the past.
Here's a full tank shot video:
A little closer in, focusing on the largest cultch:

This video is a close up of one of the tunicate colonies. That's all they do, siphon, blow out waste now and then, and contract when fish touch them. Still, I think they're cool and really enhance the aquascaping, giving more of the appearance of a living oyster reef. I will do whatever I can to keep them alive long term. I will try feeding them over the counter planktonic food for now.

Here are some pictures of the 20g long for those looking for updates and don't have time for videos. I have a couple more videos that I'll post later today. I have to do some work on them first.
Full Tank Shot:
Two colonies of tunicates (sea squirts):
A couple blennies surrounding a patch of green hair algae:
A pair of grass shrimp:
A tunicate that found its way into an empty oyster shell. It was attached to the red macroalgae (gracilaria sp.?) in the foreground. I have no idea how it wound up in the oyster shell. My hunch is that either a fish or mud crab moved it there, probably the former.
A close up of the tunicate colony:
If you zoom in on the center of the above pic, on one of the tunicates is an encrusting bryozoan colony. I can't tell if it is alive or not. I don't see tentacles, so maybe not. I hope it's alive though, that would be really cool. If it isn't, it is still encouraging because these tunicates probably spent their entire lives at this location, so the chances of me finding more live bryozoans are pretty good. I'm optimistic.

I finished with the last two videos. Hope you like them. Sorry for them being shaky at times. I was using a tripod and sometimes when you re-position the camera, the tripod sticks even though I loosened everything. I need to find another way to do it.
In this video, you can see a live barnacle at the 50 second mark:
I kept the camera focused on the largest cultch in the area where the blennies are the most active. It is fun to watch them pop in and out of their hidey holes.
Thanks for watching and checking out my thread. I hope you like the videos. I watch them every chance that I get when I'm away from my tank!
