High PH and expired PH strips
OK so I just picked up some PH test strips from the LFS which is 30 mins away. They did not have the chemical version so I was stuck with Quick Dip. I get home and see that they expired 2009/01 oh great!!! I call the LFS they tell me they should work fine. I test my PH and it says it is in the 8 range. OK how can this be? Does this mean my Kh must be high as heck? I have not tested Kh because they did not have the test kit there. My CO2 drop check is reporting that I am at 30 ppm CO2 saturation which is good. I have 2 bubble per sec on 46gal tank. Now I am a little confused here. Is the Quick tabs not working correctly?
Did not know I could have 30ppm CO2 with PH of 8 still? Is that possible?
