And once again, all your numbers look just fine :-) P03 is reasonably low should continue to drop (although probably at a slower rate) from this point onward. Ca at 410 is great. What is your target? When I was dialing my Ca in I waited an entire water change cycle to see what the total drop was between water changes, and then calculated how much I needed to dose to compensate for the Ca drop in between water changes.
