    Hey all Just got my TDS meter in the mail today. Checked the water from the tap: It reads 47 ppm. I kinda got excited!!! Seems pretty good. We are on city water, that I believe is only media filtered from our glacial lake. So 47 is kind of surprising. Thought there would be more...

    I am budget minded, so I like the $15 ones on ebay but at the same time I do not want to be buying a replacement for lack of quality. Is there any major difference between brands that I should be looking for? How often do these things have to be re-calibrated...

    I just talked with Russell at Ocean's Blend about DI resins and he strongly advocated against the use of color change media. He stated that the some of the material that makes the resin change color ends up in the source water. I was shocked because most resins available are color change. So the...
