Phytofeast culture crash?

[besskurz]

I understand this is not the best way to culture as this product is a mix of different phyto varieties. One of them should outgrown the others. This was all eexpected. I was more interested in a different variety of phyto.

But I started to have a large deposit and the water is getting clear.

If anybody out there already tried to culture, is this is normal? ( the deposit)

I think this culture went down due to lack of F2, I usually add 2ml per 1liter but maybe due to the large amount of phyto they simply exhausted the food sources?

Pods at the front, phyto after 5days or so.

I culture my own but buy fresh batches every few months to keep it healthy. After two months the stuff I bought is usually dead.

Yes this was the fresh phytofeast.

It is normal to settle out. Very fancy setup.

I was able to revive the culture with 2ml of F2.
The brown color phyto lost as expected.
Tomorrow is harvest day.

In the left side are the copepods. I'm awaiting them to breed but sounds like they are taking their time.

Harvest concluded yesterday.
I need to place a sample in the microscope to see who won

Hey just wondering opinions on Phyto feast? My LFS says its really good and cannot lead to algae blooms.

I have a feeling they are wrong.. opinions?

yeah they are wrong, sort of…
Algae blooms aren’t a function of phyto being present in the water (it would be highly unusual if it wasn’t) …
More likely a bloom following dosage might be excess f/2 or whatever …

Hello, I'm quoting a reply of reef nutrition in Reef2reef.

"We have been selling phytoplankton into aquaculture and the hobby for a long time and we have never seen anyone show us unequivocally that phytoplankton significantly reduces nitrate and phosphate, which, by the way, aren't that only things they take up. Also keep in mind, that even if they do take up significant amounts of nitrate and phosphate, you would then need to remove them from the system: what goes in must come out. Even when the algae is being consumed, not all of it is being converted to biomass which means the animals consuming it are releasing waste, which needs to be exported by normal methods"

So, it does consume nitrates and phosphates. BUT don't expect miracles.
Not overfeeding and keeping macros will also assist in the journey of nutrient recycling.
Or.. just go in the old fashion, do WC's and you will remove a portion of the nutrients too. But again.. some of it will always be present.

"Phytofeast culture crash" might refer to a phenomenon in aquaculture where the phytoplankton population crashes, disrupting the balance of the aquatic ecosystem. Phytoplankton serves as the foundation of the aquatic food chain, providing essential nutrients and energy for marine organisms. However, factors such as nutrient imbalances, pollution, changes in water temperature, and invasive species can trigger a rapid decline in phytoplankton abundance, leading to a "culture crash."

Not that what I'm about to type has anything to do with the ops question directly but to statements in the thread.
Do you ever feel like AI is invading our home here? I have noticed posts over the last few months that are exact word for word examples of the original question being asked of AI powered search engines such as copilot. Usually from newer accounts and looking at their previous posts is usually the same. I am not a conspiracy theorist but sometimes a little warning buzzer sounds in the back of my head, sounds like the robot from lost in space "Danger Will Robinson Danger". I have heard Skynet is an actual company privately funded by some larger corporations developing new AI technology.........if you know you know.

To the op I have never had long lasting good luck culturing phyto. Mostly because its usually a mix such as you have started with or the fact i'll forget to feed it or wont sterilize the container properly. Its a lot of work. Interested to see what strain came out on top.

Yes, that reply seemed like what AI would generate. Now that you mention it I'll have to keep an eye out for similar replies.

To the OP, take this with a grain of salt because I've only cultured phyto a couple of times. As my culture turns a lighter shade of green, I typically either harvest & restart or if I'm too busy I add more F2. I try to do this once a week, but sometimes it's closer to every 10 days.

I'm not certain, but I believe temp plays a role. Mine is in a cool basement, if yours is in a warmer space, perhaps it consumed the F2 quicker.

I also periodically buy more phyto, but usually it's because I've gotten busy and let my cultures go too long / crash.

Yeah that stuff was AI for sure.

The result I had would say it's nanochloropsis.

Because it's very similar in general with the other culture I have from mercer of Montana which is nanno.

I made another batch of phyto "in the brick" and I did notice that you can reach a higher density with 1ml of F2 for like 3-4 days and then add another 1ml of F2 for another 4-5 days.
Maybe I could add all 2ml at the beginning. I should try again in future.

How big is the jar and how much f2?
Natural sun light?

I have noticed a lot lately which is why I posted that. Sorry for the derail @besskurz .
