I’m wondering if my phytoplankton culture looks good so far? And wondering if the black stuff is normal.

Mine is greener, yours looks more olive, not sure if it's the pic or type of culture or perhaps the size of your bottle.
Hard to tell.
Hard to tell.
@fancy_fish101 what did you use to start your cultures?
I used this.

Not sure. This is the stuff I used and the light in using. Could it be my fertilizer? I’m using plant fertilizer.

No, it does look kinda olive oil ish.
Not sure if it’s my airline tubing too. It old airline tubing.
It’s the combination of brown and green algae, which is why it looks like that. When culturing, you really need to stick to a single strain.
I heard of that. Didn’t know it mattered that much.
So that’s why it looks like that. But is ok to have it like that?
Yes this. You'll have some die off and one strain will dominate
Can I have the 1 strain dominant and keep that strain?
Really hard to gauge when dealing with multiple strains, especially without a microscope. Theoretically one strain should dominate overtime, but how would you know when to optimally harvest the culture? Kind of hard to do that when you have strains with different colors. Even strains that are the same color are different in terms of shade. Way more trouble than it’s worth in my opinion.
So, I should restart the culture. And find 1 strain?
Where would I buy 1 strain from? And was the light I posted good enough to grow?
