RO 23? You need to replace the membrane. Should be low single digits.

Depends on what you start with . . . raw AZ water measures between 700 - 800 on my tds meter.

And as others have mentioned, Camcos filter our rocks. That's it. They don't lower total dissolved solids levels or remove minerals, chemicals, viruses or bacteria.

Either use an RO system for drinking water or for just your water tank, use a quality sediment filter with a clear plastic housing.

Why clear plastic?

So you can see when it's time to clean the filter . . .
