I have a calcium reactor set-up and have it dialled in for 24-hour operation. I have been testing my alk twice a day, once just before the lights come on and once right after the lights go out and it seems that alk consumption is higher when the lights are on and lower when the lights are off as you would expect. It looks like there is a 0.4 dkh daily swing in alkalinity. It goes from around 8.3 to 8.7 during the 12 hours that the lights are off then from 8.7 back to 8.3 during the 12 hours the lights are on.
I have noticed some acro's showing signs of stress like the tips turning brown but not quite STN and I am thinking this could be the cause. But I can't see how it is possible to get it any more stable than that without computer-controlled testing and dosing.
