Hi Jack,jalexst said:...Wait. I thought in the lights off period that many factors are involved in producing CO2... so I always had a fear that during the super long lights off period CO2 levels would rise and rise, and I would awake to see all my fish floating! (hence the "running DC down to blue" half-theory) So I take it from what to are saying that the CO2 production is not that great during lights off (in comparison to injecting at lights on)? and that the CO2 still is falling even though it is being produced at the same time? I think I remember in another post of yours that you mentioned the production of oxygen being somewhat independant of the production of CO2. So are they happening at the same time, just one outweighing the other?

Thank you so much for sharing.
Hi,I am a little puzzled by how you set up the Drop Checker with fluid and then adding water to it. I have a very basic drop checker as shown below which I just add indicator fluid to. Is this a pre mix of what you are describing throughout....
SO what your saying is test your KH and then use the chart and go across to 30ppm Co2 and see what PH that should be and then inject Co2 until you have that desired PH when the lights are on and the plants are using the Co2 the most which you test with a PH meter or Test kit?
I'll have a device folks can buy in a few weeks or so that will take that benefit and the benefits of the pH meter/probe and combine them for a 60 second 99% accuracy reading.
And that's not 3000$ USD.
