I get the phosphate thing it definitely helps algae grow so it makes sense other things would grow .. which im starting to get some red in sump I'm sure because of it. I'm not sure how your getting a 20x1 ratio. That seems a much closer than thought. If phosphate is .25ppm than nitrate needs to be under 5ppm that seems like really high phosphate and low nitrate.. am I not following on something. What are your phosphate nitrate levels?
Also as I stated last night, this is the consideration in the absence of algae. Simply nutrient levels tested on corals, ceteris paribus.
