i think its prob due to the levels of CO2 in the house. Im not sure when you have your tank lights on, but in my house, the highest point in temp is prob around noon.
Around noon no one is at my house, so I would expect this time to be when the pH level would be highest because the ambient co2 levels in the house is low.
Somehow I knew this wasn't going to be a simple answer...
For 4 days, no one was in the house, so the variables were limited. Now that everyone is at home again, I'm not sure I could repeat the same test.
My lighting schedule:
If Time > 11:00 Then BLU ON
If Time > 22:15 Then BLU OFF
If Time > 12:30 Then WHT ON
If Time > 21:15 Then WHT OFF
If Time > 17:35 Then FUG ON
If Time > 08:05 Then FUG OFF
I guess it's not a big deal. Just when I quickly googled for an answer, it appeared the ph should drop with a rise in temp. Made me curious, as that was not the experience I received.
