Well yesterday night I found a CO2 calculator that shows the ppm of CO2 present in my tank. According to the calc, my pH tested when directly taken from the aquarium - I would assume is somewhere at 6.0 or below. And if I use that calc my degrees of KH are 2 or 3 drops - which gives me a ppm of 60 for CO2. Impossible considering anything above 25 will make fish stressed, not to mention gasp for air which I haven't even seen anything close to.
The problem comes to measuring my pH. I've got an API Liquid Test kit, which hasn't failed me yet on any of my other tanks. Yet when I take a pH reading out of the tank the color is orange, which doesn't read any of the pH color card. Even if I use the high range liquid I get yellow which isn't on the chart either. Don't get me wrong, this is the ONLY tank I have had problems distinguishing colors between so far ( and I've got 6 tanks at home, not counting the ones at work ). We use the same kit at work to test water samples of customers and I've never had a issue like this.
Out of curiosity I left some water in a test tube opened, all yesterday and throughout the night. This afternoon I tested it and got a pH of 6.8-7.0 which makes more sense as the colors were a darn near match compared to the colors I was getting before. I've got two pieces of driftwood I throughly boiled, and flourite substrate. My pH out of the tap is extremely hard around 8.4
Any input on this? Is letting the water sit for abit, the correct way to test the water? IF so, are these calculators correct considering this is the 'outgased' ph level? Like I said, I get a reading that doesn't match any of the charts when a sample is directly taken and tested.
