Metalworking fluid is formulated with water that lacks any minerals.
However, tap water contains many. And, since your coolant only
accumulates more minerals over time due to evaporation (more than
5% per day by volume), water hardness, if not addressed, can lead to
problems.
Coolant Split: When a coolant split occurs, you will notice
that there is a layer of pudding-like coolant floating on
top of your sump. Your coolant concentrate is no longer
in solution, and no longer a good tool for cooling or
lubricating.
Grease Formation: Coolant, and any tramp oils
forming on its surface, may turn into a grease layer.
This layer is impossible to pick up using an oil skimmer
and can block filters and hoses.
Gummy and Soapy Residues: These may form inside
your machine and on all surfaces coolant comes in
contact with. Machine equipment and parts integrity
may be affected.

Description
Hardness Testing Sticks
Range
0-1000 ppm calcium carbonates
and/or manesium
Rust: Can damage machine interior and cause premature
part corrosion.
Foaming: This causes flooding of your machine sump
as well as a rougher environment for oil skimming, and is
caused by LOW hardness.
To avoid hardness related issues, check with your coolant supplier to verify
what hardness range your coolant can withstand and keep it there. Many
suppliers also carry a line of water softening or hardening agents, which
you can add to the sump for correction. If water hardness poses a constant
problem, consider an RO (reverse osmosis) water suppy.
