Wanting to dive into PH, I remembered the KH guardian uses PH and logs it, and keeps a "monitor" on the value.
I pulled the probe from the cup and dunked it into a cup of tank water last night at 10pm (1 hour after lights out) measured 7.9 (against 7.7 the machine was showing)
so its pretty close.
This am the machine was showing 7.5 (30 mins after lights on)
Before I do anything: I want to get an actual ph reading.
What I did and plan to do
Changed scrubber media, though color wasnt pink it was a different shade than fresh.
I want to plum a line out of the house to fresh air. Need to run 25-30 ft of airline hose.... also thinking about .... pvc with a blower fan etc. DUNNO yet. Spit balling
