Water report - brain overload !

Will do a test on fresh water and water left overnight.
Will also sort out screenshots of the water report.

According to my son who worked for a water testing company, GH is actually the measure of divalent metal ions. But the overwhelming majority of those are indeed calcium and magnesium.

correct they are Beryllium (Be), Magnesium (Mg), Calcium(Ca), Strontium (Sr), Barium (Ba), Radium (Ra). They are all colectivtly called Alkaline Earth Elements. Beryllium and Strontium are toxic at high enough levels Radium is radio active and is a product of the radio active decay of uranium. Water companies in many cases are required by law to monitor and if necessary reduce the levels of these in tap water.

Calcium and Magnesium are among the 10 most abundant elements on earth. Ba is 14th, Sr is 15th, Ra 85th, and Be 56th.

Sorry for the late response but been a crazy few days at work.

Like GH, KH has two units. Your KH is 37.5 ppm and 2.1 dH. That is quite low.

Ca I suggest you test your tap water pH - a freshly run sample, and then leave a glass of water to stand overnight and test it again. Water companies sometimes add things tto the water to temporarily raise the pH to stop metal pipes corroding. Tha water company may have tested a freshly run sample to get that pH of 8 in the water quality report.

Out of tap 8.38
Overnight 8.33
