I found an interesting online book: Pond Fertilization: Ecological Approach and Practical Applications By Christopher F. Knud-Hansen You can find it here: http://pdacrsp.oregonstate.edu/pubs/fertguide_PDF/fert_guide_TOC.html The book is about growing algae for aquaculture. The book looks thoroughly sourced. The third chapter: http://pdacrsp.oregonstate.edu/pubs/fertguide_PDF/chapter_3_of_fert_guide.pdf I found most interesting as it concerns how P, N, and C are cycled through the system and its interactions with algae. Very interesting was how algal growth significantly affects water quality both good and bad (as far as the fish are concerned).
