The ratio is actually 33 to 1 because phosphate is 31% phosphorus by weight and nitrate is 21% nitrogen by weight.
I started with no nitrates and had unhealthy corals I dropped the phosphates to 0 and have very unhealthy corals.
For now I want to get the phosphates to .03ppm and stabilize it for a while. My nitrates for now seem to want to stay at 1.5ppm
I tested my phosphates this morning and they are back down to 0 so I added another 1ml of the solution and re test it tonight.
