Water report

Certainly but this seems like only one half of the report.

Says 451ppm hardness which means youve got quite hard water not soft. All other levels are well within plant tollerances such as fluride, chlorine, lead etc.

Is there a page that deals with what this hardness is made up of ie. calcium levels etc?? This page seems to deal with just the water contaminents (i think :-) )

Hardness is a measure of the quantity of divalent ions (for this discussion, salts with two positive charges) such as calcium, magnesium and/or iron in water. There are many different divalent salts; however, calcium and magnesium are the most common sources of water hardness.

A low CaCO3 hardness value is a reliable indication that the calcium concentration is low. However, high hardness does not necessarily reflect a high calcium concentration. A high hardness reading could result from high magnesium concentrations with little or no calcium present. Since limestone commonly occurs in the soil and bedrock of Kentucky, it would be reasonably safe to assume that high hardness readings reflect high calcium levels.

A CaCO3 value of 100 mg/l would represent a free calcium concentration of 40 mg/l (divide CaCO3 value by 2.5) if hardness is caused by the presence of calcium only. Similarly, a CaCO3 value of 100 mg/l would represent a free magnesium value of 24 mg/l (divide CaCO3 value by 4.12) if hardness is caused by magnesium only. Where hardness is caused by limestone, the CaCO3 value usually reflects a mixture of free calcium and magnesium with calcium being the predominant divalent salt.

Yes i know which is why i wanted to see the part of the report that shows exact levels of CaCO3, carbonates etc etc.

This part only details contaminants like lead, fluride, chlorine etc etc, all quite standard but dosent detail its breakdown of the other ions that make up its hardness.

If you look at his picture you will see where it details his actual water hardness at 451 ppm but little else.

This is hard water on the warter hardness scale, very hard water even. My water reports have been posted here before a while back.

No that is the only page unfortunately that is why I thought I was missing something.
Give them a call say you keep fish and ask them for a better breakdown, in this modern tinternet age most companies post their water data on their company website so google for that. This is where i find my water report.
