KH, PH and CO2 levels
Hey guys....ok...I think I managed to COMPLETELY confuse myself here. I began adding co2 to my 10g a couple of days ago. When I started, my KH was between 70 and 80 ppm, PH was at around 6.6 - 6.8. I have the co2 going in at about 2.5 - 2.7 bbs.
I measured my parameters today and found the KH to be at around 120 -130 ppm and the PH around 6.2 - 6.3......now.....going by the chart that everyone seems to be using, that would mean that my co2 ppm's are WAY above what I want, like something in the neighbourhood of 107 ppm. That would seem to me that the fish would be dying pretty darn quick...and yet...the zebra danio fry are still swimming around and the 3 otto's don't seem to be breathing quickly at all. I do notice that the otto's hang around near the top of the tank quite a bit though after the co2 has been on for about 3 hours. I'm not using additives, just Aquaplus tap water conditioner and the required amount of API salt with water change.
What am I doing wrong? Should I lower the bbs on the co2?
