How to maintain water in resovoir at correct ppm?


#1

I was doing my normal tests today and it came to me after reading an article on ph and ec. My ph is at a good range of about 6.2 and my EC is at 1.6 but my ppm when I tested it was 1060. Almost 1000% of what it should be. Any ways I can correct this or can I just leave it. What should I do soldiers??

PPM is measured with a TDS meter. Ec with an EC meter.

1.6 EC can be about 1050-1200 ppm
