Has anyone had problems with the calcium numbers not being in line with other testers ? Mine continues to read high, the last actual number I got was a 573.60 after that every test just reads “hi” Tried new reagents and strips, no different than the rest of them
numbers depend on which calcium test you are using, they have 2 calcium test kits and calcium range is different, 1st calcium test kit range is up to 500 ppm and second is Calcium, UH Marine Kit (as CaCO3) which has range from 730 - 1500, if your test kit is showing HI that means it is above 500 and second test kit will be able to give you the correct reading if it is higher than 730,
@eXact iDip® - Please correct me if I am wrong
