Ok either this makes no sense or I am on to something, so co2 changes your ph depending on the amount of co2 your putting in the tank. At one point the ph will be stable but at night time plants stop using co2 but the fish are still producing co2. With no air stone co2 is going to continue to build up. With a airstone it help removes co2 and provide more o2 with surface agitation, which once again would change your ph a little depending on the amount of bubbles and surface agitation . End theory if I turn co2 off at night but turn on air stone to a low setting I should be able to get a balance between co2 and o2 during the day and night to keep my ph stable. How does this sound??????
