Already did. And already dosed with spectraside. P04 however did not budge after weeks of testing with over feeding. Thus the need to dose Brightwell NeoPhos. The higher, now elevated level of Nitrate (now holding steady around 7 - 10) and lack of P04 caused some issues in my sps .. this is why I knew that over feeding was not going to do it and I needed to dose.I agree that slightly elevated levels of nutrients are beneficial but I think you're missing a decimal point. The school of thought is that you want just enough NO3 and PO4 to not starve the coral but not enough to promote algae outbreaks. Systems with higher nutrient levels that show little to no nuscience algae growth typically have huge colonies of coral with very little room to spare. The coral is outcompeting the algae for nutrient use. I think good target numbers for the average reefer attempting to keep SPS corals should be around 3-5ppm NO3 and .02-.03 PO4. Check out the spectracide stump remover thread for lots of discussion on this matter.
I get the ranges and where it should be at ... I was just curious if others knew how much P04 their systems used due to the swings mine was going thru.
