I have just started adding CO2 via a DIY yeast fermentaion system

I checked the KH & PH prior to starting up the CO2

The KH was about 10 and the PH about 7.8

I assume both these figures will start to fall within a few days of adding CO2

I Read that KH should be maintained somwhere between 4 & 6 is this correct??

what is the suggested way of maintaining this? i read some people add bicorbonate of soda to increase the KH others talk about crushed coral

i am going to purchase a continuous use digital PH meter, but how often should i be checking the KH level?

sorry if these questions seem over dumb, but it is important for me to get it right from the start, as i dont want to lose any of my fish stocks due to silly mistakes
