I recently got a TDS meter Tank is 9 months old and during that time a majority has been used with distilled water to mix my salt mix. Walmart distilled water measured 7 ppm, LFS rodi measured 1 ppm, and just for some fun tap water was 440 pm. I have been using strictly rodi for the last 3 weeks. Im assuming the diatoms have been fueled by the distilled water having a high level of TDS. What are y’all thoughts? Also is this RODI water good enough with 1 ppm of tds for the tank?
