I just got a water tester for Tds and was totally blown away I thought I had super hard water all this time but my reading was 80 out the tap nothing hooked up no softener or anything I have a RO/DI unit it read 0 after the RO and of course 0 out the DI. And out of the reject water it was reading exactly 100. Is this good enough to grow discus up or do I need to add anything . Thank you John
