What can make water look hard while not testing as hard?
When tested with the API GH test kit it is less then 1 degree hardness.
The water leaves these white minerals everywhere, which eventually build up on pipes and hoses, especially the hot water. Leaves white crap all over the dishes. It also leeches metal from brass fittings and causes then to crack and leak.
Recently I suspect is was responsible for ruining an RO membrane which dropped down to 50% efficiency within a few months of light use.
It is well water and the pH is 4.5 consistently. TDS is around 100.
Attached image is a hose that is caked with these mineral deposits. Mostly white with a little rust coloration.
- Is it possible there is something else in the water that is giving an inaccurate reading on the test, the pH for instance?
- What kind of test is more precise that can tell me what minerals these are?
- Also, is the low pH a result of these minerals, or is that a separate issue entirely?
- Should we get a softener or a neutralizer, or both?
Main issue is that I cant keep buying RO membranes every few months when they are supposed to last a year o r more.
