Our tank's biology up close

Here's he playlist for this one
https://www.youtube.com/playlist?list=PLN_wI2B-a8vrmoReObEvAUgYrVJdHmKW1


few times here
Just after 2 minutes a tiny one just kind of "pops" into the big one
Just after 2 minutes 50 seconds another merger with a slightly bigger one
Just after 3 minutes 40 seconds another one

And here he comes with another merger and stretches along the strand of cyano

The other night, I think it was Saturday, I wanted to see what a single strand of algae with a drop of vibrant on it would do.

I wasn't expecting much and can't really say the vibrant did anything of what I saw but it was a pretty cool thing to do and found some bacteria liking certain areas. Even saw pieces of something (the algae?) falling apart covered in bacteria. Again, I can't say for certain it was the bacteria in the Vibrant or just bacteria that didn't get washed off.

What I did was pick a small strand of algae out of my ATS and rinse it in freshly mixed saltwater. And rinsed again. And rinsed again. And again. And again. It certainly got rid of most everything else I normally see.

I still need to get the videos uploaded.

Now this set was cool to watch and have it on video (hopefully) The pieces being "pulled" out of the algae.

Google decided to animate that sequence. I still need to get the videos uploaded.

And this was the cool one.

Right about the 2 minute mark I try to see where these little pieces are coming from. Then realized they were coming from the algae...


Right after the 3 minute mark I caught a nice chuck come out.

Back to Bacteria in a bottle. I've looked at Instant Ocean Biospira, Dr. Tim's one and only, and Dr. Tim's Eco Balance.

Of those it was only the one and only I didn't find any bacteria but plenty of detritus.

Tonight I'm looking at Microbacter7. It reminds me a lot of the Eco Balance but there is visually some differences in some of the bacteria.

I'm going to try this product on my reef, I have a little cyano, and very small patches of hair algae. I keep my nutrients pretty low, barely detectable if at all. I want to know if these products help with the nitrogen processing by improving the bacteria diversity. We shall see.

Until now trimming my ATS and chaeto was a sad moment, as I knew that I threw away, a lot of useful organisms. Seeing you photos make it a lot worse.
 
I'm interested in the Vibrant test. Btw your work here is interesting and important!

I think I've narrowed down what this smaller dinoflagellate is. I've suspected a type of Amphidinium.

From the description in this paper I'm thinking it's Amphidinium massartii. Some really cool images in this article too.
https://www.researchgate.net/public...om_the_temperate_waters_off_Jeju_Island_Korea

From it:
Amphidinium massartii Biecheler (1952) and Amphi-
dinium carterae Hulburt (1957) are small and have some-
times been considered to be con-specific (Murray et al.
2004, 2012). However, Murray et al. (2004) suggested that
A. massartii is clearly different from A. carterae because
A. massartii plastids are centrally located and are pres-
ent at a relatively low density, while A. carterae plastids
are peripherally located and reticulated. In addition, they
also suggested that flagellar insertion of A. massartii (~0.6
of the cell body from the apex) is situated in a lower po-
sition than in A. carterae (~0.4 of the cell body from the
apex).

From their toxicity testing:
Toxicity analysis
No nauplii of A. salina were dead after 48 h of incuba-
tion with A. massartii AMJJ1 concentrations of 100, 500,
1,000, 5,000, or 10,000 cells mL


Another good article with images of various dinoflagellate around Jeju island as well.

I have what looks like a dusty dark dirt like area on my substrate where my last bit of cyano was during my Vibrant testing and I wanted to see what all was there.

Pics and vids uploading. I will give a little spoiler because I was very excited to find them. I finally found a couple ostracods with eggs. Very cool looking.
 
So, it mostly looked like well... dirt. It was a lot of detritus with some cyano, diatoms, sponge spicules, lots of bacteria of different types etc. Normal detritus stuff I see.

But I did find some cool stuff.

I followed this little ciliate for quite some time. It was very excited spinning very fast.
