I don't DIY my DC or solution but I have my Co2 come on 3hrs before lights on after realizing it takes about 2˝~3hrs for mine to become mint tea green in my 90gal, open overflow and open sump setup. After lights out mine goes back to blue in 4~5hrs.

- how frequent should one change the the 4 dKH solution and reagent?
Thanks!

No the DC isn't realtime but proper co2 evels can be
assumed correct if DC is green. Recently through much reading here I have come to realize there are other factors such as plant uptake, plant mass as well as flow that can affect reatime levels.
I usually change my solution every 2 weeks max 3.
