CO2 messing with Ph

[bob`_your_dog]

Hey I just wana know if a CO2 maker could be causing a Ph problem, because my Ph was round 7.5 i think and i been running the CO2 for about 2 weeks and i did a water test today and found my Ph ant 6.8 !!!!!! And my nitrite levels are now 0.3 !!!

Yes, CO2 will lower the ph. Do you happen to know what your kH reading is? You want it to be at least 3-4° to prevent the ph from crashing. The decrease in ph to 6.8 is normal. I don't know about the nitrite reading, but I think it's unrelated to CO2.

Great reply from Bangin. There are some great articles about this very topic on the Krib. Yes, it can lower your ph... I've no idea that it has anything to do with nitrite readings...
