Hi
This was my last pH profile (2 bps, inline diffuser, 60 cm tank, spraybar, DC yellow at lights on; probably improved by now as I have lots of biomass and I have increased the bubble rate) and you can see what happens when I switch off my Co2 one hour before lights off
It's incredible how fast the Co2 is lost... I was wondering, especially when I increase the bubble rate from 2 to 3 bps, if Co2 can be switched off two hours before lights off. My guess is that even if the co2 is rapidly degassed plants will have more than enough with 5 hours of Co2 super pumping. But my guess is that this can be very difficult to measure, I mean if 2 hours before lights off plants will suffer for low CO2 levels. I know UKAPS tutorial says that the last part of the photoperiod is not so important but... when do you switch off your CO2?
