Alk is at 9.5dkh. It went up from about 8.5 naturally when I brought my nitrates up. I have added very little buffer in several weeks
I haven't been using GFO since April 13, since my phosphates zeroed out.
I am currently checking nitrates, phosphates daily, alkalinity every other day and calcium twice a week.
My calcium requirements have more then tripled.
I checked everything last night
Alk-9.8dkh
Calcium- 450
Nitrates -1.5ppm
Phosphates at .006ppm or 2 ppb phosphorus on hanna ULR
