I knew about the ro water from the stores, but did not know about the bottled water.
These are "total dissolved solids"...................................
Here is a post I made a few weeks ago on another discussion about water. I don't really think any bottled water can compare with ro/di. Definately check out the SUMMARY OF NRDC'S TEST RESULTS link!!!
As I said I called and they do not use copper. Everytime I read this comment I picture a backhills whiskey operation.
NRDC: Bottled Water - Appendix A
Hinkley shows 1.9ppm nitrates. I wouldn't use it, or any of them, not even Evian, the one I thought would be one of the best choices, which clearly isn't!!
This is what DI is:
What does DI, Demineralization mean and what does it do?
(Usually of interest to reefkeepers and chemists) Demineralization by Ion Exchange. Employing a mixed bed media made up of both Anion & Cation resins ions, salts or minerals can be entirely removed from water . The standard R.O. membrane can be relied upon to remove (95 - 98 %) of the minerals found in water. When you could follow the membrane up with a D.I. cartridge you can expect almost 100 % removal of the TDS .
The percent of rejection of your membrane will have a direct impact on the life of your DI cartridge.
In plain language the DI absorbs everything left behind by the reverse osmosis membrane . Our DI will allow you to produce water of incredible quality, down to (0) ppm of total dissolved solids.
ok so make that Hinkley water drinking water and go to Meijer and get some RO!
Sorry if you already answered this but are you testing the water after you add the salt or before?
I tested after the salt was added.
