Keeping a stable kH in low ph
I need to get my ph down to 6.5 - 6.7 for the livestock I keep. I do however, want to keep the kh between 3 - 6. Is there anyway to achieve this balance?
I inject co2, my tap water is soft but neutral. There is a bag of crushed coral in the filter. I have both Seachem Buffers which can get me to the ph I want, but technically not the kh, since the Acid Buffer turns kH into Co2.
