Dude f/2 means 2mls per litre litres of new water. So your F2 is not f/2 it's super concentrated version of

Thank you very much for giving us part of your time and doing this great work.

You can use poop to fertilise. Just use a few pieces of chicken fertiliser pellets.

You forgot to go over how to recover a crashing culture! Wtf!

Use a funnel

How can we achieve 0 tds ? I have at best 2tds :)

Can you feed daphnia with this

Do you fliter the air, to prevent contamination ? Would adding co2 be a good idea?

Is the 150 micro too big though... I thought copepod ranges from 100 ~ 500 micron

Great video... Like#191

Rotifers cant

Thanks for the video :) One slight error I noticed - F/2 does contain copper, just in very small trace quantities (approx. 10 micrograms CuSO4 per litre of final medium). Also there's a good reason for F/2 to sometimes be shipped in weaker form - keeping certain components below 1% avoids it being classified as hazardous. Things you wouldn't know unless you looked in to making it ;)

👏 beautiful explanation. Thankyou.

Do you reuse the rigid airline tubing or is it always a new piece when you start a new culture or split an old one? Been having slight issues with contamination but im not sure if it is because of that or because of outside particles being sent in from the airline tubing. All of mine are in 2L bottles capped off but there is obviously a small opening so air can leave.

Nice... 👍👍👍

Hi everyone, i consume marine phytoplankton as a supplement. I want to start to grow my own from the supply i have so i dont have to keep buying it. is f/2 formula safe for human consumption. as in if i feed this to my plankton, in turn is it safe for me? thanks

How do you know when the current culture is going bad or what not? If you have extra, do you just dump some away, dilute, and regrow?

Where you got the mesh?

Hello! Can I ask you about the lighting? On how many Kelvin do they emit? What's the best for growing phytoplankton?

What aeration did you use? CO2 or O2?

Simply brilliant

Get a bigger filter funnel

Nice tip. Thanks.

I'm interested in the edible ones 😎

You mentioned that if a culture crashes it starts to turn clear and you also mentioned that you can fix it with the F2 fertilizer how do you go about doing that do you just add F2 fertilizer after you filter it and then put it back in a clean vessel and put the air on it again?

Any differences in breeding freshwater equivalents?

great information; thank you.

Loved the video! Very informative :) I do have one question though, how do you determine how much f/2 to add to a culture?

how do you get the clean salt water? od you use every day ocean water

hi there good video i have tried to log onto the site but always comes up with an error

Thanks. Nice clear video.

what do you sterilise with.

Where did u buy your mesh? You forgot to tell us

any best dptt for fresh water algal identification and its ecology

Hi you can tell me why the seaweed is in the bottom and the transparent water has a good sounding and intense light what can I do

once cultured, how long will it last in the bottle?

what temperature is better ?

Best Phytoplankton Culture vid I've seen. Very informative and good detail about using RO water (0.0 TDS) and how there's copper in fertilizer. Couple of questions, do you culture more than one type of phytoplankton? How long do you light your culture each day? You also never elaborated on how you can save a culture that's started to crash. You only mentioned feeding but nothing specific.

What kind of light did u used?

Hi how often do you need to replenish the F2, and once you extract say half the phyto do you just replenish the saltwater and add 1ml of F2 Great and informative video

can humans eat it?

Does the phytoplankton have any smell to it?

what do you use for your air pump, and are you pumping co2 or air in? ive heard of people using both.

What is your ratio for your culture?You mentioned 1 liter of culture, then added x liters of saltwater.

Did I hear you right? 1.9 to 2.0 for your salinity?

how do you sterilize ?? please?

I can't find your website and I would like to see videos on rotifers please

Great video! Do you culture any type of copepods?

Hi, great tips, can you make a video for a Copepods culture from the start to finished stage in a bottle?
