nightly ph drop

[Craigdillman]

is it causing anyproblems cause most tanks drop PH at night its natural and nothing to worry about, the ocean dose it. In the day there is a excess metabolic demand therefore increse gas exhange and in turn raise in PH while at night there is a slowing of everything and there for the ph drops and becomes more acidic .... unless you see a problem it probably did that way longer than when u strated to mesure it
