Myka's 90 gallon build & 3 province move (Pics Feb 6)

[Myka]

Today's testing results (all Salifert):

Calcium 350 ppm (oops, my dosing is off apparently )
Alkalinity 8.45 dKH on old kit
Alkalinity 9.45 dKH on new kit
Magnesium 1185 ppm on old kit
Magnesium 1320 ppm on new kit
Nitrate 0.2 ppm (this is not usually detectable)
Phosphate undetectable
Potassium (forgot to test)


So, I have to adjust my dosing. The new alkalinity kit is interesting because it comes with a 7.4 calibration solution. The new kit reads 7.4, and the old kit reads 6.4, which agrees with the difference in testing above. So that's interesting. I am concerned about the HUGE difference from the old to new magnesium kits. I tried to retest with the old kit, but I didn't have enough reagent. So now I'm not sure...???

My targets are; calcium 410-420 ppm, alkalinity 8-8.5 dKH, magnesium 1350-1375 ppm.

Current Zeo dosing (changes due to increased water volume):
Sponge Power 1 drop daily
Coral Vitalizer 1 drop daily
Coral Snow 3 mL 2x per week
