What I did this week:
- used the calculator to adjust Mg in all tanks to 1350
- took three days to add all the Kent Mg to each tank
- have been dripping kalk for the last two evenings and nights in all tanks
- have been dripping 1/2 kalk and half RO during the day in the 120g for top up.
Test results from this afternoon:
37g: (water change will be on Sunday)
- dKH - 6
- pH - 8.11
- magnesium - 1440 ppm
- calcium - 360 ppm
67g: (water change will be on Sunday)
- dKH - 7
- pH - 8.25
- magnesium - 1335 ppm
- calcium - 400 ppm
120g: (water change will be on Sunday)
- dKH - 8
- pH - 8.32
- magnesium - 1335 ppm
- calcium - 400 ppm
Comments:
- unexpected rise in Mg in 37g
- Mg about where I thought it would be in 67g and 120g
- alk decreased in all cases to varying degrees
- Ca either increased or stayed the same
