Around here we discourage the use of anything to adjust pH except:

CO2: lowers pH
Baking soda (sodium carbonate): Raises KH, which raises pH


In that case would you advise the use of a CO2 diffuser instead of a PH
buffer.? Could baking soda be used directly in the water without endangering
the water's balance?




Lime (calcium carbonate): Same effect as Baking Soda, also raises GH
