I have been able to maintain my nitrates at .5ppm for 5 days. I have been adding 40mls of the KNO3 solution daily.
My phosphates have dropped off the chart. I am almost using no GFO and my phosphates were .003ppm. Still too low. Before I started raising my nitrates my phosphates were over 2ppm and I was using a ton of GFO to keep it respectable. So just for controlling phosphates this is a win.
The colours of my corals are getting better.
This blue matrix was brown before I started adding nitrates.

These pictures were taken from above, the other picture were taken from in front and I fixed the white balance on my camera. They are still not show quality but the colours have improved quite a bit.
