FraserNZ Posted July 4, 2011 Report Share Posted July 4, 2011 Hi guys, Over the weekend I setup my new CO2 system. I removed my breeding pair of ram before installing it on the tank as I didn't want to take any chances of a PH swing effecting them. I think I have it running at the correct amount of C02 as the drop checker I have changed to the correct color. I have tested the PH & KH before the system was added this reading was 7.2ph with 2.0KH After the system had been running for a day the PH dropped to 5.9 with the KH at 1 drop (Test was taken just before the system cuts out when the lights are turned off) The next morning I measured the PH and this had increased to 6.7. Is this an acceptable swing or would this be concided bad for fish? Quote Link to comment Share on other sites More sharing options...
kiwiplymouth Posted July 4, 2011 Report Share Posted July 4, 2011 A PH swing of around 1 deg is about right to achieve a co2 level of 25-30ppm This chart is a helpful tool too Quote Link to comment Share on other sites More sharing options...
Artem Posted July 6, 2011 Report Share Posted July 6, 2011 A Ph swing of one degree is meant to be alright with most fishes, so it should be fine. Quote Link to comment Share on other sites More sharing options...
