Wade Posted September 23, 2013 Share Posted September 23, 2013 What's the normal PH swing throughout the day and night? My PH will peak at 8.24 at about 5:00PM and bottom out at 8.12 at about 5:00AM and then start to climb back up around 9:00AM when the lights start ramping up. I don't suppose a .1 swing throughout the day is too bad is it? I run my refugium light at night to offset the swing and my LED moon lights stay on at about 3% all night.

jestep Posted September 23, 2013 Share Posted September 23, 2013 .2 - .3 per day. Pretty consistent fluctuations with temperature and lighting cycles. Link to comment Share on other sites More sharing options...
Richard L Posted September 23, 2013 Share Posted September 23, 2013 0.12 pH swing is small. Nothing to worry about here. Link to comment Share on other sites More sharing options...
