so my15 drops turns blue , then I need to add more calcium?Hey Gettie!
15 drops should be 300 ppm, in the back of the book youll see a conversion chart.
Start with 15 drops, cap and shake your test tube, and then continue drop by drop and shake in between each.
Yes, you should try to aim for 380-450ppm.so my15 drops turns blue , then I need to add more calcium?
my 15 drops shows 300 ppm according to chart should be 19 drios for 380 ppm so If turn blue @ 15 drops is this too much calcium or need more ?Could you send a picture of the chart? Any API calcium test kit chart I looked up has 15 drops as an option... Maybe I am not understanding?
