Almost the same as my tap!
Clean your diffuser or replace it and see what happens to your Ph.Keep in a
dark place or near the bottom of your tank. Test the Ph in morning and the
evening to see how much it travels and decide how much you want it to travel
and adjust with the CO2. It will move around here and there no matter what.
If you are happy ........then you are fine!

If your happy don't mess with it. I bet you tested your water at night
before the light went out.
I'd clean that disc and see that it's making nice small misty bubbles near
some water flow at the bottom of your tank. Bet that Elodea, hornwort, lace
and Crypt does well though............all good harder water and or lower
CO2 plants............this is the key for you I would suspect.
