BRS's TDS-3 TDS Meter

[clancaster23]

Does anyone else have Nulk Reef Supply's TDS-3 TDS meter and if so, how does it work? Mine is always reading in the 100's! I just put all brand new filters and carbon in my ro/di system and it still reads in those high areas. I tested new water out of the filter and it'll go in the 100-110. That's basically the same as my tap water. I'm guessing either I'm not using it right (I'm sure I am) or maybe it's faulty or something. Anybody else have it and have the same problem?

Now if I test the water in the five gallon jug that I just filled through my system it reads 007 which is good but I feel it should say 000 considering these are brand new filters. Should I expect the 000 reading or is 007 acceptable?

I believe that any reading less than 10% of the source water is considered acceptable - so if your source water is reading higher than 70, your reading of 007 is acceptable

Do you have a DI canister on that RO unit of yours? And what are you testing the jug with?

 

[clancaster23]

Yes there is a DI canister and it has been changed also. All three filters are new. It's this one: 75 GPD RO/DI 4 Stage Economy System - English

IS it connected right? The input on the red and the out put on the blue line?
