I recently joined up and I wish to ask a question about water changes and ph. As per Tom's recommendation on another forum, I recently added CO2 to my 30 Gallon Long (about 6 hours ago) and my ph is headed down very slowly (I have it set at about 25 bubbles per minute and will adjust if necessary). I religiously perform a 50% water change weekly and since my city water has a rather high ph (7.8), and I will be keeping my ph around 6.75 to get the desired ratio of CO2 with my KH of 4, will the rapid ph change be a problem for my fishees? If so, what would you recommend. I have 4 cardinals, a ram, 6 otos, 2 cory juliis, 3 diamond tetras and 1 female betta in my aq. By the way, is that too high a fish load in your opinion?
Thanks,
Mike Herod
