Tap water PPM to RO or not to RO.
    #442504 - 07/06/10 06:52 PM (6 years, 4 months ago)

Hello folks,

I got my EC meter today and my PPM @ 700 conversion is 280 PPM I believe General Hydroponics considers tap water to be hard when it's 300+ ppm but I think 280 is very close.

Should I use RO or use their hardwater micro?

If I get a RO unit I want one that splits my faucet so I can pour tap or RO.

Thanks,
MA3087

Something was wrong with my first measurement the actual ppm is 70.

really? 70 is fantastic water, mine here is 65 and people can't believe how great it tastes. You'll be fine without an RO

For like 35minues it was sitting at 70, then I pulled the probe and put it back in and it doubled to 140. It seems to sit at 140 now. I tried my trucheon also and it was at 140 but that's also it's lowest reading. :P

I hope this meter isn't wonky. I'm going to get some calibration solution tomorrow and figure out something for a reservoir of some sort so I'm not mixing 2gals of nutrient solution at a time.


Edit: Turns out I had some calibration solution and it's spot on. I think the lower reading had to do with the tap water coming out colder than the probe and the probe needing time to adjust to the same temperature.
