So I recently invested in a spectrapure RO/DI unit to finally have control over my water parameters. For some reason the PH doesn't behave the way I believe it should.
TDS of the DI is 0, PH 8.2. The source is very hard well water that passes through a water softener, before the softener its GH > 25, KH > 20, TDS 650, PH > 8.
I've remineralized using Salty Shrimp GH+KH to
GH 7,
KH 5,
TDS 220.
In my tank with Aquasoil, with a lime green drop checker the PH measures 7.2. It would rise to above 8 again if left sitting out overnight. There's also mopani driftwood in this tank. My Small non co2 tank is PH 8.2 with slightly softer water param, GH 5 KH 3. No aquasoil in this one. Nothing in either tank is causing KH increase.
Sigh..
