I have dKH at about 7.9 - just done an ICP to confirm my Hanna Reading.
I'm aiming for dKH in the range 7.5 to 8.5. The Red Sea Recipes have either 12 dKH or 8KH and for a long time I've switched to a salt that is doesn't have an elevated dKH.
I have just started to become aware of pH. I originally tested when setting up but then never tested it again assuming it didn't matter (or wasn't easily changed).
The value of pH in a quarantine tank is 8.3 but in my DT it is closer to 8.0. I probably need to remeasure it when lights are about to come on and as they go off that corresponds to start of activity and end of an evening in my Sitting Room where DT is located e.g., CO2 affecting the pH.
What is the value in changing the dKH e.g. elevating it to 9, in controlling/buffering properties vs pH?
