my PH which averages 8.25, with a daytime high of 8.33 dropping to 8.24 approx. preciseley at 09.30 each day it drops right down to approx. 8 for a minute or so then shoots back up to around 8.2, i have checked with charts on my Apex for any relation with temperature and ORP, nothing relates to the time drop, i have checked dosing time and the only one that coincides with it at 09.30 is the Red Sea NO Pox which starts at 09.00 and ends after 10ml at 10.00, any suggestions to what could be causing this?
one thing i should add is that there is no change to the tank area room lighting at that time,
