That's what I was thinking. Also a home RO/DI unit is advisable. I was getting water hauling buckets befroe I got one, it gets old fast. When my unit arived it had a TDS meter with it. I checked what was left of my LFS water and it read 22 TDS, it went down the drain, now I get 0 to 2 TDS all the time.
