SRC Member akahoshi Posted January 7, 2007 SRC Member Share Posted January 7, 2007 Why does the water's pH level drop at night and morning? Is it because of a rise in carbon dioxide? Quote Link to comment Share on other sites More sharing options...
mansiz Posted January 9, 2007 Share Posted January 9, 2007 Is your lightings off during morning and night? Ph do drop a little when lights are off, thats why many people drip kalkwasser during this period which can main Ph and maintain calcium as well. Or probably get a 24 hr refugium, probably it helps.
