When it comes to "nutrients" of nuisance algae in a display, which is more influential, nitrate or phosphate?
For example, if I want to keep my nitrate up a little, for the sake of the zooxanthellae in my SPS, is eliminating PO4 my primary means of eliminating nuisance algae? I'm wondering, and I may be confusing myself here, but where is that threshold between healthy algae I want and healthy algae I don't want?
