I realize PH drops a night and mine usually went from 8.07 to 8.20 but now mine is swinging too much, at least I think. It is going from 7.77 at night to 8.40 during the day. Has anyone else ever experienced this?
Other info: Calibrated my PH probe twice.
And only recent changes are: Added four pieces of old sun dried live rock (about the size of half dollar each) to my sump. Use them for frag plugs. And added new T5 bulbs about a 2 ½ weeks ago. Haven’t seen the PH change until this past weekend so I don’t think it’s the lights?????
Thoughts/help?!
