1.5 year-old Biocube 29, probably 26g of water. Last week, these were the parameters:
NO3: 0.5ppm
PO4: 0.01
Alk: 11.2 (Salifert)
Alk: 10.2 (Hannah)
Ca: 390
Mg: 1350
pH: 8.34
Temp: 77.6
Salinity: 1.025
So I reduced the alk dosing from 13mL/day to 11mL/day and increased the Ca dosing from 13mL/day to 14mL/day, expecting the alk to be lower and Ca to be higher.
One week later, these are the parameters:
NO3: 0.5ppm
PO4: 0.01
Alk: 12.1 (Salifert)
Alk: 11.1 (Hannah)
Ca: 340
Mg: 1290
pH: 8.36
Temp: 77.5
Salinity: 1.025
I don't understand why the results are opposite from what I would expect. What is going on here?
