I finally set up my co2 and the problem i'm having is that by the chart. starting with ph 7.8 kh 3. set the controller to 6.6ph to get around 23ppm. Problem is that when I test ph with the test kit and one of those seachem ph monitors in my tank it still shows 7.8. the controller shows 6.6ph. Also the temp normally is around 77deg but last night the temp dropped to 69deg and my ph took a dive to 5.4??? Any ideas????

i calibrated it when i first got it and it was fine. i pulled it out last night and checked it with tap water and it 7.8 out of tap and it was way off . i ordered some 7.01 ph test solution, but for now i adjusted it to 7.8tap.maybe i didn't let the probe break in the first time? what do you think???? thanks for your help
