Grunden til mit spørgsmål er at hvis man bruger Caulerpa til at optage fosfat vil den samtidig også fjerne nitrat, og efter hvad jeg kan læse mig til vil den faktisk fjerne mere nitrat end fosfat (se nedenfor) derfor kunne det måske være en ide at bruge lidt fosfat fjerner (f.eks rowaphos e.l.) samtidig med at køre med Caulerpa. Spørgsmålet er blot om man kan risikere at fjerene for meget fosfat og derved mindske væksten af Caulerpa'en og derved risikere øget nitrat?

/MagnusFor those interested in knowing how much phosphorus is being exported by macroalgae, this free PDF article in the journal Marine Biology has some important information. It gives the phosphorus and nitrogen content for nine different species of macroalgae, including many that reefkeepers typically maintain. For example, Caulerpa racemosa collected off Hawaii contains about 0.08 % phosphorus by dry weight and 5.6% nitrogen. Harvesting 10 grams (dry weight) of this macroalgae from an aquarium would be the equivalent of removing 24 mg of phosphate from the water column. That amount is the equivalent of reducing the phosphate concentration from 0.2 ppm to 0.1 ppm in a 67-gallon aquarium. All of the other species tested gave similar results (plus or minus a factor of two). Interestingly, using the same paper's nitrogen data, this would also be equivalent to reducing the nitrate content by 2.5 grams, or 10 ppm in that same 67-gallon aquarium.
