I am still trying to get to grips with co2 and got a question regard PH, if I'm right there should be drop in PH when co2 on then it should stabilized when the lights are on? Over the last week I wasn't able to dial the co2 in due to working hours and didn't want to risk so I did run it on very low side, 1bps but noticed that the drop checker was dark green almost blueish, and that was 1h before light, the following day tried 2h and still same colour, not sure if I done right but today, I cranked to 3bps and started the co2 2.5h before lights, I was checking with torch how the drop checker was responding, and was happy with the result, looks to be lime green about 30min before lights come on so I could maybe drop the co2 time down a bit but if you think I should just leave it then I will.
Now on to PH when lights are off with co2 off I get 7.4ph, lights off co2 on after about 1h the ph started to drop calling to API test kit, sorry don't have any kind of pen, I tested every 30 min and it had steady drop until reached 7.0-6.8 colours are just to close for my eyes to give you most accurate reading. Lights on and after nearly 3h now drop checker still lime green and I would say PH is 6.8.
Is this normal for the PH to drop and I guess it will raise again once the co2 is off?
