Any one have tips on Culturing Phytoplankton?
I've been watching videos about it, and they recommend using F2 Fertilizer because it's "Reef Safe" but all the F2 fert. I can find has copper in it. Do I need fertilizer or just a good growing light?
Also how long do you recommend the lighting to be on? 12 hours? more or less?
Any tips or links to other threads/post would be great thanks!
