Review: Good Product - Works like a charm
Review: My chlorella vulgaris is blowing up in density! - This stuff has helpled my chlorella vulgaris culture grow wonderfully! And its sheer size could last me multiple decades based on my math (which hopefully isn’t flawed)! Overall, wonderful product! Would recommend for any phytoplankton or algae culture!

### ⭐⭐⭐⭐⭐ Concentrrated.
*by R***A on January 24, 2026*

I find this formula of F2 to be nicely concentrated. The amount to add to a culture, per their instructions, has worked well for me with my Nannochloropsis algae.
