Please correct me if I am wrong, but the way I understand the effect of CO2 on Ph is that even though the CO2 lowers the Ph reading in the tank, it will have no effect on the fish. That is, what effects the fish are the Gh and Kh and that the CO2 simply spoofs a temporary Ph reading until it dissipates.
That being said, I want to follow Tom's advice and crank CO2 during lights on and shut it off during the night. This will cause my Ph reading to fluctuatae between 8.1 and 7.2. I keep Tanganyikan Cichlids that like a high Ph (assumed related to Kh and Gh), but can I really induce this level of extreme flutuation without consequences.
I have cranked down the controller to as low as 7.5 and since doing so have lost two Cyprochromis Leptosoma and a Neo. Gracalis. All other water parameters are in line; no amonia, no nitrites, frequent water changes etc. Could it just be coincidence these fish died? All the fish look and act fine.
So, can I fluctuate Ph by .9 daily through CO2 injection without harming the fish assuming all other parameters are fine and there are no diseases?
Thanks to all....
