Hi - I’ve added a DI filter to my RO system in order to get my Nitrates down.
I use a 75:25 ratio of RO to tap water (in order to keep my nitrates around 5ppm) but that leaves me with a Kh if 2.5 and a Ph of 7.4.
I’m worried that a Kh of 2.5 might not be high enough to prevent Ph swings.
From what I can tell I can’t increase the Kh without increasing the Ph and 7.4 seems like the right place to be.
Is my Kh alright or should I try and increase it? If so what’s the best way to do it?
Thanks!
