My ph stays consistently at around 8.2. I can't lower it no matter what I try - I guess because of the KH and GH. I am putting in new plants that like the ph to be more neutral - like 7.6 or so. how do I get it lowered? By putting in less kh?


I dose weekly with: KH and sometimes GH, thrive liquid fertilizer, stress coat and zyme



My water parameters currently:
PH; 8.0 - 8.2
KH 7
GH 7
