F/2 fertilizer has copper.

[Dr. Dendrostein]

Hello, everyone, I'm culturing nannochloropsis. Culture started 5 days ago. Just found out f/2 food has some copper. Should I feed to corals the algae that's been cultured?

I didn’t know F2 had copper in it. I feed my Phyto cultures F2. Haven’t had any problems with my corals. Everything seems to be growing just fine... I’m going to try a culture with skimmate rather than F2 to see how well the culture does.

Right, we'll see what happens. Thanks for the info.
