Ive seen timers that will regulate the amount of bubbles per second. Im not sure if its out there...i would imagine it would be, but perhaps you could get a counter that cuts back the amount over night. Just in such a way that the ph doesnt as everyone has mentioned rise. That way you could leave it on all night, but have it decrease to just the point where you arent having such flucations. A drastic increase in a short period of time causes a great deal of stress....a stressed fishie in the morning would probably be about the same as i am without the first coffee...nasty

I thought i would just add. Out of curiosity, with the unit on or off at night, how much of a ph fluctuation do you guys see. Im not currently using a co2 setup, i have in the past but scrapped it. Is it a full 1.0, or are we talking 10ths of a ph here? Just your own findings, thanks.
