HI I guess I am still a little confused as how that reads CO2 in the water a general wall mount reading room present co2 is not going to be the same as what is dissolved in the water. also if your tank is a planted fresh water tank and is having very low Ph one thing to try is stirring up the bottom I hade a similar problem a while back and it was all caused by dead spots under some large drift wood pieces I had the break down reaction was generating a weak acid and over time it beat out the waters ability to buffer I was killing myself to figure it out and the local fish stores where no help really they just wanted me to keep buying buffers. Hope this might help I had to tear down half my tank to fix it 180G tank no fun doing that
