pH went down for no reason?????
For some reason my pH is down to 7.4-7.8 from 8 where it was. I've been testing exactly the same way (test tubes), and I haven't done anything different. My tank is practically done cycling so that's the only change. My tap water shows 7.8 pH, the same it did a month ago (water co says it's 7.76).
Will it go down when the nitrites get to zero? Which is the only coinciding event that has happened. I really don't think that's true, but can't think of any other reason.
oh. I did change how the air pumps were running, from all the time, to just on at night. maybe that change the releasing of CO2 and helped our pH to go down.
I DON"T KNOW!!! weird!
Thanks everyone. I'm really not upset, I'm actually really happy, cause the fish I want are 7.0 pH fish. But I also want it to stay down and not go back up!
