I ordered stuff to culture my own phytoplankton. I did the strain Nannochloropsis because it's the easiest to grow and everything eats it. Also, it contains a Zeaxanthin cartenoid alcohol which enhances multiple colors in livestock as well as containing an astaxanthin pigment which does the same. I got an eight ounce bottle of phyto, an air pump and a fertilizer.
I am hoping with the addition of dosing RS AB+ and now live phytoplankton my corals do great. Some are and some aren't thriving. I hope this makes all of them thrive.
