Phyto Crash?

[Brandon Rush]

Can anyone tell me if this phytoplankton culture looks like it's crashed?

Can you turn off the leds and light with regular lights?

Also, is it getting lighter instead of darker? If so- something is eating it. If it’s changing color and getting a lot of debris- it’s more likely to be nutrient exhaustion.

Using F/2 to provide nutrients?

It does a bit - are those white LEDs and what are you using for aeration/water movement?

If it looks like it’s turning yellow or brown it’s starving and you need to add some more fertiliser

A newly split thin culture looks the same. It’s impossible to tell with that light and knowing what it looked like previously.

I think you're right I used the same amount as my first batch but this one has gotten lighter. Is it too late to save?

This is my second batch, did everything as the first. Using a air pump with 1/4 tubing. White striped lights.

No. Add some more food and it’ll come back. It can stay in ‘stationary phase’ for a few days at room temp if no light, and a couple weeks in fridge. If you add fertilizer now, it’ll start growing again

Seems like it's gotten lighter, opened it up and it doesn't smell. I think maybe I just didn't put enough fertilizer.
