    Default pH and PPM rising

    I have cleaned my GH Water farm for the 3rd time and I still and have problems keeping the pH and PPM down. Right now I am running plain water in it. I started it yesterday with a pH of 6.3 and a ppm of 93. Today it is running 7.3 and 240. I have no plants in it just water. I boiled everything and made sure it was clean.

    What can be causing this?

    Default Same issue

    I have same issue. What are you using for media? I'm using 2/3 hydroton and 1/3 coir in a Dutch Bucket drip system, similar to a Water Farm, using GH nutrients. Let me know if you found anything.

    I guess ppm and ph will swing in opposite directions. PPM dropping if the solution is not strong enough.A total average for the expedition of 299,6 ppm.

    Did you add any nutrients to water before you took those readings?
