Hello , I'm measuring CO2 on the top of the tank with a PH meter like this
https://www.ebay.com/bhp/ph-meter-atc
Anyone knows what the difference in co2 can be from the bottom of the tank to the top of the tank ?
I cannot introduce the ph meter completely in the water to measure ph at the bottom of the tank
Thanks
