Here’s a quote from @taricha
Do test kits (PO4 & NO3) test for organic or inorganic?
I want to shift the majority of my available nutrients to inorganic forms and I want to filter out most of the organic forms.

Question: do skimmers and filter socks remove organic or inorganic N & P?Dinos are good at uptaking complex (organic) forms of N, and less good - relatively at taking in simple (inorganic) forms. Green algae is the reverse - better at taking the simple stuff, and worse at the complex organic forms of N. And it looks like the story may be similar with P.
