50 gallon calcium update

[Josh23]

Well I tested my water today and this is what I found. It came to me as being a little suprising. Went a little something like this.......

Temp 79
Salanity 1.024
Ammonia 0
Nitrites 0
Nitrates 0
Phosphates 0
Alk (KH) 160 mg/L (ppm) not sure how to calculate this to meq/L
Ca 560 (wow its off the chart) I dont know what I was doing before but this is the first time I have ever got a reading like that.

Does anyone know how to convert the KH.
Thanks
Josh
