I continue to add phytoplankton daily, but haven't started any testing (Total N, Total P, etc.) - I'm having some issues with tank pH (nothing to do with phytoplankton additions) - I suspect it is the new pH probe (not ATC.)Any updates on this ? I'm very curious about this as I would like to a create greater food web and bio-diversity in my mixed reef and wonder if this could help with that. My end goal would be to keep scleractinian (?) corals and sea fans long term.
